Multiply 30 -- the number of years of the loan -- by the number of payments you make each year. For example, 30 X 12 = 360. You are making 360 payments over the course of the loan. Divide your mortgage interest rate by your total payments.
I think that it would be A
3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
answer: y= 2x^2+2x-4
steps:
y= (2x+4)(x-1)
*FOIL method* y= (2x^2-2x+4x-4)
*simplify* y= 2x^2+2x-4
