Answer:
cos²A - cosA - 6
Step-by-step explanation:
Given
(cosA + 2)(cosA - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
cosA(cosA - 3) + 2(cosA - 3) ← distribute both parenthesis
= cos²A - 3cosA + 2cosA - 6 ← collect like terms
= cos²A - cosA - 6
Answer:
$35.90
Step-by-step explanation:
It is easy homie
The given equation is

To solve for x, we have to subtract 8 to both sides

Now we need to get rid of -9 from the left side, and for that we do division
