Answer:
(x - 9)(x + 3)
Step-by-step explanation:
Given
x² - 6x - 27
Consider the factors of the constant term (- 27) which sum to give the coefficient of the x- term (- 6)
The factors are - 9 and + 3, since
- 9 × 3 = - 27 and - 9 + 3 = - 6, thus
x² - 6x - 27 = (x - 9)(x + 3)
39° because a right angle adds up to 90°
Answer: B. 12
Step-by-step explanation:
f(x) = 3x2 – 7x + 2
f(- 1) = ?
f(-1)=3(-1)^2-7(-1)+2
=3(1)+7+2
=3+7+2
=12
