Step-by-step explanation:
7a2 + 10a − 3a − 2a2
Combine like terms
742 + 10a - 3a - 2a2
742 + 7a - 2a2
solution=
5a2 + 7a
Answer:the answer would be 7.38
Answer:
C
Step-by-step explanation:
Like terms mean same variable. it doesnt really matter if its negative in the front.
Step-by-step explanation:
When -16t² + 32t + 75 < 75, -16t² + 32t < 0.
=> 16t(2 - t) < 0, t < 0 or t > 2.
However t < 0 is rejected as time cannot be a negative value. Hence the solution in interval notation is (2, ∞).
