Answer:
(x - 43)(x + 3)
Step-by-step explanation:
consider the factors of the constant term (- 129) which sum to give the coefficient of the x- term (- 40)
the factors are - 43 and + 3 , since
- 43 × + 3 = - 129 and - 43 + 3 = - 40 , then
x² - 40x - 129 = (x - 43)(x + 3) ← in factored form
Answer:
a. Slope is -2/7
b. b = 1
c. y = 2x + 1
Hope this helps :)
Step-by-step explanation:
A is correct:
Let volume v, length l, and h height.
v= (l²h)/3
v=(x²9)/3
v=3x²
Two million,two hundred one thousand ,seven hundred sixty
3.5x=42
x represents the length, since the formula to find area of a rectangle is width times length.
