<span>(5x^7 y^2)(-4x^4 y^5) =-20x^a y^b
</span><span>
solve this:
(5x^7 y^2)(-4x^4 y^5)
= -20 x^(7 + 4) y^(2 + 5)
= -20 x^11 y^7
answer
</span>A) a=11, b=7
4 goes into 26 6 times with a remainder of 2.
26 ÷ 4 = 6 2/4
6 2/4 = 6 1/2
Your answer is 6 1/2

128+7=135
135=100%
10%=13.5
1%=1.35
13.5-(3×1.35)=9.45
I believe that 9.45% is the answer
