Answer:
y = x² + 3x - 40
Step-by-step explanation:
Given the zeros are x = - 8 and x = 5, then the factors are
(x + 8) and (x - 5) and
y = (x + 8)(x - 5) ← expand factors
y = x² - 5x + 8x - 40, hence
y = x² + 3x - 40 ← in standard form
Answer:
y=−2x−10
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
4.20 / 4 = 1.05
105 x 9 = 9.45
(X+3)^2+(X-2)^2=9................
