Answer: They would make $28.76.

Explanation: If 7 video games are worth $100.66, when you divide 100.66 by 7(100.66/7) you get the amount of money that 1 video game would be worth which is $14.38. Multiply 14.38 by 2(the number of video games they sold) and you get the answer of 28.76(the total money they made).

The length of a rectangle is twice its width. if the area of the rectangle is 128 ft2 , find its perimeter.
kupik [55]
Length(l)= 2w
Width(w)= w
Area(A) = l*w

A= 128 ft²
128= l*w
128= (2w)w
2w²= 128
w²= 64
w=√64= 8 ft
w= 8 ft

length(l)= 2w
l=2(8)
l=16 ft

P= 2l+2w
P=2(16)+2(8)= 32+16= 48ft
P= 48ft

Answer:
The Perimeter of this rectangle is 48 feet.
