Pls help me!!! I need to find what b is??

Answer:

14x + 23

Step-by-step explanation:

The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.

The perimeter of a triangle: the sum of all of its sides.

5x + 9 + 2x + 14 + 7x

14x + 23

It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.

Answer:

  √89

Step-by-step explanation:

The Pythagorean theorem relates the measures of sides in a right triangle. For legs 'a' and 'b' and hypotenuse 'c', it tells you ...

  c² = a² +b²

  c² = 5² +8² = 25 +64 = 89

  c = √89 . . . . the length of the third side

Answer:[tex]\sqrt{89}[/tex]

Step-by-step explanation:

opposite=8

Adjacent=5

Hypotenuse= ?

Using pythagoras theorem,

[tex]Hyp^{2} = Opp^{2} + adj^{2}[/tex]

[tex]Hyp^{2}[/tex]= [tex]8^{2} +5^{2}[/tex]

[tex]Hyp^{2}[/tex]=64 +25

[tex]Hyp^{2} =89[/tex]

Take the square root of both sides.Square and square root will cancel out leaving Hypotenuse

Hyp=[tex]\sqrt{89}[/tex]

The attached figure is drawn to scale, and a grid is provided that makes it easier to see the dimensions of the various parts.

This figure can be easily decomposed into an overall rectangle with cutouts of a trapezoid at the top and a rectangle at the bottom right.

__

The overall rectangle has dimensions 8 units wide and 10 units high.

The trapezoid at the top has bases of 8 units and 7 units, and a height of 2 units.

The rectangle at the bottom right has dimensions of 4 units wide and 3 units high.

The area formulas for a rectangle and trapezoid are ...

  A = LW . . . . area of a rectangle with length L, width W

  A = 1/2(b1 +b2)h . . . . area of a trapezoid with bases b1, b2, and height h

__

Then the area of the figure is ...

  figure area = overall rectangle - trapezoid - lower right rectangle

  = (8 in)(10 in) - 1/2(7 in + 8 in)(2 in) -(4 in)(3 in)

  = 80 in² -15 in² -12 in² = 53 in²

The area of the object is 53 square inches.

The slant height of the square pyramid that has a surface area of 304 sq. in. is: 16 inches.

Surface area (SA) = a² + 2al

Given the following parameters:

Plug in the values into (SA) = a² + 2al:

304 = 8² + 2(8)l

304 = 64 + 16l

304 - 64 = 16l

240 = 16l

240/16 = l

15 = l

l = 16

Therefore, the slant height of the square pyramid that has a surface area of 304 sq. in. is: 16 inches.

Answer:

a. 120 Degrees

b. 180-120=60 60 Degrees

Step-by-step explanation:

A straight line has a maximum of 180 degrees.

ABC is 120, so CBD is 60

a) The size of angle ABC is 120 degrees.

b) The size of reflex angle CBD is 240 degrees.

a) The size of angle ABC is 120 degrees by inspecting at the protractor and counting from 0° 1o 120°

Reflex angles are formed by extending one of the sides of an angle beyond the straight line, creating an angle greater than 180 degrees. They can be visualized as the "extra" portion of a rotation around a point, beyond the 180-degree mark

b) To determine the size of reflex angle CBD,  consider that a reflex angle measures more than 180 degrees but less than 360 degrees. Since angle ABC is 120 degrees, subtract this angle from 360 to find the remaining measure of the reflex angle CBD.

Reflex angle CBD = 360 degrees - 120 degrees

= 240 degrees.

Therefore, the size of reflex angle CBD is 240 degrees.

A finite, nonzero area formed by the lines would have a fixed measurement

The number of separate region that have a finite, nonzero area is 64

The given parameters are:

The number (n) of separate region that have a finite, nonzero area is calculated as:

n = (h - 1) * (v - 1)

This gives

n = (9 - 1) * (9 - 1)

Evaluate the product

The scale factor when a triangle of 8cm side is enlarged to a triangle of 64cm side is 8.

Side of the first triangle = 8cm

Side of the second triangle = 64cm

A scale factor is a number by which the size or dimension of an object is enlarged or diminished.

For example, if an equilateral triangle with a side x is dilated by a scale factor of 2, the enlarged size of the side will be 2a.

So, scale factor = side of the second triangle/ corresponding side of the first triangle.

Scale factor = 64/8

Scale factor = 8

Therefore, The scale factor when a triangle of 8cm side is enlarged to a triangle of 64cm side is 8.

Answer:

-4 and -16

Step-by-step explanation:

Let x = first number

Let y = second number

Given:

⇒ xy = 64

Given:

⇒ x + y = -20

Rewrite  x + y = -20  to make x the subject:

⇒ x = -20 - y

Substitute into xy = 64 and solve for y:

⇒ (-20 - y)y = 64

⇒ -20y - y² = 64

⇒ y² + 20y + 64 = 0

⇒ (y + 4)(y + 16) = 0

⇒ y = -4, y = -16

As x + y = -20

If y = -4 then x = -16

If y = -16 then x = -4

Therefore, the two numbers are -4 and -16

The amount which Brandon have saved in interest by consolidating the two balances on the card with the lower interest rate is $256.12.

Monthly payment is the payment which has to paid against the loan amount or the borrowed money calculated with interest rate.

It can be calculated with the following formula.

[tex]M=P\left (\dfrac{r}{1-(1+r)^{-nt}}\right)[/tex]

Here, (P) is the principal amount, (r) is the interest rate and (t) is time.

Brandon has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest rate.

The table below shows the information about the two credit cards Brandon currently uses.    

Interest rate for the card a is,

[tex]r=\dfrac{13}{12\times100}=0.01083[/tex]

The time period is 8 years and there are 12 months in one year. Thus, the monthly payment of card A will be,

[tex]M=1157.98\left (\dfrac{0.01083}{1-(1+0.01083)^{-12(8)}}\right)\\M=19.47[/tex]

In the 8 years, there is total 96 monthly payments. Thus, the total payment by card A is,

[tex]P_a=19.47\times96=1869.12[/tex]

For the card B the monthly payment is $22.14. Thus the total payment by card B is,

[tex]P_b=22.14\times96=2125.44[/tex]

The difference in the payment is,

[tex]d=2125.44-1869.12\\d=256.12[/tex]

Hence, the amount which Brandon have saved in interest by consolidating the two balances on the card with the lower interest rate is $256.12.

The equation solved by the John to find w, the greatest width in centimeters he can use for the mosaic, is w(w + 2) = 48.

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of the rectangle and (b) is the width of the rectangle

The area of the tile is 48 square cm. John wants to make the mosaic with this tile having the length 2 cm longer than the width.

Let the width of the rectangle mosaic is w cm. Thus, the length of it is,

[tex]l=w+2[/tex]

As the area of a rectangle is the product of its length and width and Tte area of the tile is 48 square cm. Thus,
