Answer:
150+12x=630
Step-by-step explanation:
The x represents the amount of months and it is multiplied by 12 because each month costs 12$. 150 have to be paid up front and this added to the monthly fee is equal to 630$
3, assuming 2x2 is 2x squared, u will get
4 + 6x3 - 10x2
So 3 terms
P/9 = 90
Multiply 9 to 90 to isolate the variable.
P = 9 x 90
P = 810
I don't understand it sorry
