Answer:
2x*x
2x*-5
1*x
1*-5
2x²-10x+x-10 add numbers that have similar variables
-2x²-10x+x-10
=[-2x²-9x-10]
F(-3) = -2(-3)^2 - 5(-3) + 4 = -2(9) + 15 + 4 = -18 + 19 = 1
50/80, then divide it by ten so the answer is 5/8. Once the number can divide both numbers your good.
It’s 663.48 because if you divide 276.45 by 5 than you get 55.19 and multiply that by 12 and it’s 663.48
