Answer:
4x² + 4x - 2
Step-by-step explanation:
The opposite is the negative value
The opposite of - 4x² - 4x + 2 is
- (- 4x² - 4x + 2) ← distribute parenthesis by - 1
= 4x² + 4x - 2
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.
Answer:
x = -3/4
Step-by-step explanation:
<u>Step 1: Identify the equation</u>
8x + 3 = 4x
<u>Step 2: Move x's to one side and number to the other side</u>
8x + 3 - 4x - 3 = 4x - 4x - 3
4x = -3
<u>Step 3: Make x by itself</u>
4x / 4 = -3 / 4
x = -3/4
Answer: x = -3/4
