Answer:
D
Step-by-step explanation:
multiplying f(x) × g(x) = (2x² + x - 3)(x + 2)
multiply each term in the first factor by each term in the second factor
= x(2x² + x - 3) + 2(2x² + x - 3) ← distributing gives
= 2x³ + x² - 3x + 4x² + 2x - 6 ← collect like terms
= 2x³ + 5x² - x - 6 → D
Step-by-step explanation:
use the pythagoras theory.
a2 + b2 = c2
the firth one use this formula
a2 = c2 - b2
a2 = 10.6² - 5.6²
a2 = 112.36 - 31.36
a2 = 81
a = 9
The same method use to the eighth one
