The area of a rectangle is represented by 63x^{3}+9x and the length is represented by 7x^{2}+1 . Find the width of the rectangle in terms of x.
Answer:
Step-by-step explanation:
[tex]7x^{2} +1 = 15x[/tex] and [tex]63x^{2} +9x= 135x[/tex]
so, divide because to solve for area you multiply so the opposite of multiplication is division, Anyway so [tex]135x/15x=9x[/tex]
Hope this helps.

If the perimeter of square 3 is 36 units and the perimeter of square 2 is 48 units, what is the area of square 1?
Answer:
225
Step-by-step explanation:
length of side in square 3 = 36/4
=9
length of side in square 2 = 48/ 4
= 12
using pythagorus theorem you can find side of square 1
take the triangle between 3 and 2
9^2 + 12^2 = length of side 1^2
81 + 144 = l^2
225 = l^2
l = 15
therefore length of side 1 is 15
area of square 1 = 15^15
area = 225 square units
hope this helped

I’m confused I’m not sure which one it is
Answer:
A.55
Step-by-step explanation:
Because DE parallel to AC m(<B) common angle So ABC similar to DBEm(<D) = m(<A) = 180 - (60 + 65) =55Ria solves the equation 5 + 3r = 4 + 4r and gets r = r. She concludes that the
equation has infinitely many solutions. What is the correct solution? What mistake
did Ria make?
WalMart offered a 15% discount off the regular price of a Ice Cream Maker. The amount of the discount is $5.00. What is the regular price of the Ice Cream Maker?
Answer:
$33.33
Step-by-step explanation:
We are told in the above :
WalMart offered a 15% discount off the regular price of a Ice Cream Maker.
The amount of the discount is $5.00.
The formula for Percentage Discount =
Discount/Original amount × 100
Original amount = x
Hence:
$5/x × 100 = 15%
= 5/x = 15/100
Cross Multiply
5 = 0.15 × x
5= 0.15x
x = 5/0.15
x = $33.33
Therefore, the regular price of the Ice Cream Maker is $33.33

Answer:
A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
An exponential equation is written as:
y = A*(r)^x
Where A is the initial quantity and r is the rate of growth.
If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.
They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.
1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Answer:
B
Step-by-step explanation:
x- intercept = 2 .So, Coordinate(2 , 0)
y-intercept = 8 . So, Coordinate (0, 8)
[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]
Slope y-intercept form: y = mx + b {Here, b is y-intercept}
y = -4x + 8

a boat travels 45 miles east then 60 miles north how far is it from where it started
Answer:
SOLUTION: A boat travels 45 miles east then 60 miles north, how far is it from where it started. Draw this. The hypotenuse of the right triangle is the square root (45^2)+(60^2)=square root of 2025=3600=square root of 5625, or 75 miles. If you divide 45 and 60 by 15, you get 3 and 4, and the hypotenuse is 5.

ayo um can i get help Please just show your work and tell what the area is
Answer:
320 inches
Step-by-step explanation:
First, split the figures into 2. 1 short rectangle and long rectangle.
Find the area of the longer rectangle first.
Length = 16 + 8 = 24 in
Breadth = 16 - 8 = 8 in
Formula for area of rectangle = Length x Breadth
24 in x 8 in = 192 in (Area of long rectangle)
Find the area of the short rectangle.
Breadth = 16 - 8 = 8 in
16 x 8 = 128 in (Area of short rectangle)
Since they're combined,
192 + 128 = 320
I don't know if this is correct, but I hope it was helpful)
Mindy looks outside her window and sees limp tomato plants in the garden. She quickly waters the plants, and by the end of the day, the plants are upright with firm stems. How did watering the tomato plants straighten the stems?
Answer:
Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.
