Answer:
-36x² - 8x - 8
Step-by-step explanation:
Distribute 6x and -8 through the parenthesis:
-48x + -36x² - 8 + 40x
Collect the like terms:
-8x - 36x² - 8
Use the commutative property to reorder the terms:
-36x² - 8x - 8
Answer:
A. positive -positive = positive
X = -12
First is moving the -15 over with the 93 by adding it on both sides. The equation will look like this: -9x = 108
Then you’ll divide by -9 and get x = -12

Answer:
Probability that Caroline buys fruit, a CD or both is 0.76.
Step-by-step explanation:
Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.
Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.
Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.
Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.
