Answer:
-2p² - 9pq + 6q²
Step-by-step explanation:
Add the like terms
p² + - 3p² = -2p²
-7pq + - 2pq = -9pq
-q² + 7q² = 6q²
Answer:Multiply the top equation by -3 , then add the questions .
Step-by-step explanation:
Total hats = 52 + 13 = 65
Percentage that are baseball = number of baseball/ total hats x 100.
52/65 = 0.8 x 100 = 80%
80% are baseball hats
4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
Csc theta=-2 then theta equals csc^-1(-2) then theta would equal 5pi/6, 7pi/6
