Answer:

x = 12

Step-by-step explanation:

Step 1: Define

f(x) = 2x - 7

f(x) = 17

Step 2: Substitute

17 = 2x - 7

Step 3: Solve for x

Add 7 on both sides: 24 = 2x

Divide both sides by 2: 12 = x

Step 4: Check

f(12) = 2(12) - 7

f(12) = 24 - 7

f(12) = 17

Find the area of the shaded region. Round to the nearest tenth if necessary

Gwar [14]

The area of the whole rectangle is 91cm. Subtract 2 because of what is not shaded in the bottom right, then subtract 12 from what is not shaded in the top left. That leaves you with 77cm of shaded area.
