I need help solving this (4a^2+6a+9)(2a-3)
Answer:
a = 3/2
Step-by-step explanation:
Solve for a over the real numbers:
8 a^3 - 27 = 0
Hint: | Isolate terms with a to the left hand side.
Add 27 to both sides:
8 a^3 = 27
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by 8:
a^3 = 27/8
Hint: | Elminate the power on the left hand side.
Take cube roots of both sides:
Answer: a = 3/2

Answer:
Step-by-step explanation:
From the table attached,
x-intercept of the linear function is, the value of 'x' when f(x) = 0
x = 3 [x-intercept]
Function 'g' is the sum of 2 and the cube root of the sum of three time x and 1.
g(x) = [tex]2+\sqrt[3]{3x+1}[/tex]
For x-intercept,
g(x) = 0
[tex]2+\sqrt[3]{3x+1}=0[/tex]
3x + 1 = (-2)³
3x + 1 = -8
3x = -8 - 1
3x = -9
x = -3
Therefore, the x-intercept of function 'f' is different or greater than the x-intercept of function g.

HURRY NEEDED BY SATURDAY
Answer:
42°
Step-by-step explanation:
the exterior angle is equal to the sum of the 2 far angles from it (from the exterior angle)
so 98-56=42°
hope you understand it
Answer:
42
Step-by-step explanation:
line TZY is a straight line
Total angles on a straight line is 180
Since angle XZT + XZY = 180
98 + XZY = 180
XZY = 82
angle XYZ + YXZ + XZY = 180
XYZ + 56 + 82 = 180
XYZ + 138 = 180
XYZ = 180 - 138
XYZ = 42

Find the area of a circle that has a circumference of 12π in.
Answer:
a = 1.91
Step-by-step explanation:
12 = 2π(r)
12/2 = 2π(r)/2
dividing by 2
=
6 = π(r)
you then divide this by π, or 3.14
6/3.14 = π(r)/3.14
=

By applying Pythagorean theorem to the sides of the right triangle, which has sides as a, b and c, where c is the
hypotenuse, we get
a.) c^2= a^2+ b^2
b.) c^2= a^2– b^2
c.) c^2= a^2 - b
d.) c^2= a^2+ b
=
[tex]c {}^{2} = a {}^{2} + b {}^{2} [/tex]
where,
[tex]c = hypotenuse[/tex]
[tex]a = perpendicular[/tex]
[tex]b = base[/tex]

Which value in the set [4, 9, 15, 36] is a solution of 12 = 3 + x?
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12=x+3
Step 2: Flip the equation.
x+3=12
Step 3: Subtract 3 from both sides.

The inner circle circumference is 52 ft. the distance between the inner and the outer circle is 8ft. By how many ft is the outer circle larger?
Answer:
The outer circle is 16 feet larger than the inner circle (68 - 52).
Step-by-step explanation:
Given that the inner circle circumference is 52 feet, and the distance between the inner and the outer circle is 8 feet, to determine by how many ft is the larger outer circle, the following calculation must be performed:
The radius of a circle is equal to half its diameter. Therefore, the radius of the inner circle is 26 feet. Thus, if the distance between the two circles is 8 feet, the radius of the outer circle is 34 feet (26 + 8). Therefore, the diameter of this circle is 68 feet (34 x 2).
This implies that the outer circle is 16 feet larger than the inner circle (68 - 52).

A rectangular boad is 1100 millmeters long and 900 millmeters wide. what is the area of the board in square meters?
Answer:
1100 mm = 1.1 m, and 900 mm = 0.9 m.
So the area is 1.1 x 0.9 = 0.99 m^2
The area of the rectangular board is 0.99 square meters.
Given that a rectangular board is 1100 millimeters long and 900 millimeters wide.
We need to find the area of the board,
To find the area of the rectangular board in square meters, we need to convert the given dimensions from millimeters to meters and then calculate the area.
Given:
Length of the board = 1100 millimeters
Width of the board = 900 millimeters
To convert millimeters to meters, we divide the given values by 1000:
Length in meters = 1100 mm / 1000 = 1.1 meters
Width in meters = 900 mm / 1000 = 0.9 meters
The formula to calculate the area of a rectangle is:
Area = Length × Width
Substituting the values, we get:
Area = 1.1 meters × 0.9 meters
Area = 0.99 square meters
Therefore, the area of the rectangular board is 0.99 square meters.

Ed bus a box of eggs costing £2.30, two packs of bacon for £2.60 each and two tins of baked beans. He pays with a £10 note gets 80p change how much did the tin of beans cost?
Answer:
£0.85 for each
£1.70 for both
Step-by-step explanation:
Variable x = cost of baked beans
2.30 + 2(2.60) + 2x = 10 - 0.80
Use PEMDAS
2.30 + 5.20 + 2x = 10 - 0.80
7.50 + 2x = 9.20
Subtract both sides by 7.50
2x = 1.70
Divide both sides by 2 to isolate the variable
x = 0.85
Let's check our work by plugging this into our original equation
2.30 + 2(2.60) + 2(0.85) = 10 - 0.80
2.30 + 5.20 + 1.70 = 10 - 0.80
7.50 + 1.70 = 9.20
9.20 = 9.20
Our number is correct
PLEASE HELP!!!! Parallelogram
Answer:
B) 120 degrees
Step-by-step explanation:
The two triangles are the same, so first find the measure of angle B.
To do this first solve for angles A and C. Solve for A first: 4x or 4(5), which is 20 degrees. Now solve for C: 8x or 8(5), which is 40 degrees. Add 40 + 20 degrees to get 60 degrees total of those two angles.
A triangle has 180 total degrees, so to solve for the measure of Angle B, subtract 180 - 60 to get 120 degrees.
Since the two triangles are the same, Angle D is the measure as Angle B.
