X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3
Answer:
Option D, Yes, Devon should have evaluated f(3)
Step-by-step explanation:
f(x) = x^3 + x^2 − 10x + 8
<u>Step 1: Evaluate using F(3) NOT f(-3)</u>
f(3) = 3^3 + 3^2 - 10(3) + 8
f(3) = 27 + 9 - 30 + 8
f(3) = 14
Since the factor is (x - 3) the x value is x - 3 + 3 = 0 + 3 -> x = 3 not x = -3
Answer: Option D, Yes, Devon should have evaluated f(3)
Answer:
She can fill 9 boxes, and will have 4 cookies left over.
Step-by-step explanation:
9 x 12 = 108.
112 - 108 = 4
