Solve for x. what is the measure of each indicated angle? show your work

x is equal to 7

the measure of both angles is 23°

Step-by-step explanation:

1. set both equations equal to each other

2. 4x - x is 3x

3. 16 + 5 is 21

4. 3x = 21

5. divide both sides by 3

6. x equals 7

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
