The answer is 2x³ + 12x² + 10x - 24
(2x² + 6x - 8)(x + 3) = x(2x² + 6x - 8) + 3(2x² + 6x - 8) =
= 2x³ + 6x² - 8x + 6x² + 18x - 24 =
= 2x³ + (6x² + 6x²) + (-8x + 18x) - 24 =
= 2x³ + 12x² + 10x - 24
Nah that’s right a is the correct answer
Answer:
74
Step-by-step explanation:
Create rectangles by moving triangular pieces around:
Triangle A fits at location A', so you get a rectangle of 9*6 = 54 ft²
Triangle B fits at location B', so you get a rectangle of 5*4 = 20 ft²
totals to 20+54=74 ft²
If you’re solving for x, it’s x=2,-4
