How do I solve for x ?

x = 4

Hi there !

use Thales theorem

x/(x + 8) = 4/12

12x = 4x + 32

12x - 4x = 32

8x = 32

x = 32 : 4

x = 4

4/(8 + 4) = 4/12

4/12 = 4/12 (true)

Good luck !

-6 is the correct option from the above given options

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
