x = 17.56

Step-by-step explanation:

The relationship of these lengths can be demonstrated using this equation:

18(18 + x) = 16(16+24)

(The first smaller length multiplied by the first full length should equal the second smaller length multiplied by second full length).

Using this equation, we can solve for x and end up with 17.56

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.
