Step-by-step explanation:

Question 10 :

3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)

simplify and get x, thus x = 18

to find 3x + 6 or 4x - 12(which is both the same),

3(18) + 6 = 60° , 4(18) - 12 = 60°

Question 11:

2x + 24 + x = 180 ( reason: interior angles due to parallel lines)

simplify again to get x, you will get x = 52

then find the individual by subbing in the value of x into the equation.

so 2x + 24 = 2(52)+24 = 128° and x = 52°

The equation above can be used to calculate the volume V, of a cone with a height h and radius r. If the volume of a cone is 243

WARRIOR [948]

Answer:

The height of the cone is $h=9\ ft$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

In this problem we have

$V=243\pi\ ft^{3}$

$r=h\ ft$

substitute

$243\pi=\frac{1}{3}\pi (h^{2})h$

simplify

$729=(h^{3})$

$h=\sqrt[3]{729}\ ft$

$h=9\ ft$

The x-intercepts of the gravy of f (x)= x (x+1)(x-5)(x-7) are

Serhud [2]

"Of the gravy" lol

To find the x-intercepts, you make f(x) = 0 and solve for x by setting each factor equal to 0.

0 = x(x + 1)(x - 5)(x - 7)

x = 0

x + 1 = 0
x = - 1

x - 5 = 0
x = 5

x - 7 = 0
x = 7

Your x-intercepts are x = - 1, 0, 5, 7

OR

There are x-intercepts at (- 1, 0), (0, 0), (5, 0), and (7, 0).

Multi step equations 4x+6+3=17

Kobotan [32]

First, you add like terms. In this case, the like terms are 6 and 3.

4x + 6 + 3 = 17
4x + 9 = 17

Then, subtract 9 on each side:

4x + 9 - 9 = 17 - 9
4x = 8

Then divide by 4 on each side to get the x by itself:

4x/4 = 8/4
x = 2
