X=first number
2x= second side
3.5x= third side


X+2x+3.5x=65

6.5 x= 65
Divide both sides by 6.5

X=10. First side
2x= 20. Second side

3.5x= 35 = third side

10, 20, 35

Choose the correct simplification of the expression a^7b^8/a^4b^4
Alex787 [66]
The answer is B: a^3b^4<span>

Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)

Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)

7 - 4 = 3:
a^3 b^(8 - 4)

8 - 4 = 4:
Answer:  a^3 b^4

PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (<span>a^7b^8)/(a^4b^4)</span>
