A.


192 = (9)(13)




B.


192 = (9)(13 + x2)


C.


192 = (9 – x)(13 – x)


D
192 = (9 + x)(13 + x)

Answer 4

D

Answer 5

no medal until you explain

Answer 6

and tks

Answer 7

It would be D. The reason is that the formula for the area of a rectangle is A = l times w. The new area you would like to see is 192, the "A" in our formula. If you want to increase the length and the width by the same amount, keeping in mind that you don't know what the amount is, it would increase both by x. That's why.

Answer 8

Area = length*breadth
Let the increment in the sides be x then
new length = 13+x
new breadth = 9 +x
new area = 192
so 192 = (13+x)*(9+x)
