The answer is 30 because you have to multiply the two together
12 = 12/1 = 24/2, 24/2+1/2=25/2 so 25/2, and it's in simplest form because 2 can't go into 25
25 x 0.1 = 2.5 ≈ 3
25 + 3 = 28
The machinist would make about 28 on Wednesday
Just jump the gun and multiply -7 and the value of d
-2[7x^2-24]-31
I got
-14x^2+17
as the total answer btw...
