I’m pretty sure it is the first one
Simplifying
h(t) = -1t2 + -2t + 30
Multiply h * t
ht = -1t2 + -2t + 30
Reorder the terms:
ht = 30 + -2t + -1t2
Solving
ht = 30 + -2t + -1t2
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by 't'.
h = 30t-1 + -2 + -1t
Simplifying
h = 30t-1 + -2 + -1t
Reorder the terms:
h = -2 + 30t-1 + -1t
Answer: Is this completing a a square?
Step-by-step explanation:
The equaton for cost is
first website is 1.25x
2nd is x+3
I'm assuming what number of songs wil make them have same cos

0.25x=3
divide both sides by 0.25
x=12
answer is 12 songs must be purchased to spend the same on each website
