2x² - 3xy
2(1)² - 3(1)(2)
2(1) - 3(2)
2 - 6
-4
Multiply 5x136 than add answer plus 348 take the total 3000- the total post answer in comments ill tell u if right
42.7/7= 6.1
36.48/6=6.08
7.29/9=0.81
Answer:
f+g is right answer.
Step-by-step explanation:
given
,
2x+3 is given and we have to find the combinations of h,f and g.
By trial and error we check h+f
= -4x-2
h-f = 10x-6
So these two are not correct
Try with h+g = 12x-3 and h-g = -6x-5
Hence these are also not right
Try with f+g
(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3
Hence f+g is right.
