Let: x = width of picture
then: length = 2x
and based on the information:
2(2x) + 2(x) = 120
4x + 2x = 120
6x = 120
x = 20
So:
Width = 20in
Length = 40in
Therefore:
Area = 40 × 20
= 800in²
KX = x+4 so solve for k.
Divide both sides of the equation by x and you get K=4.
Plug it in, and you get (4)(7)=28
Your answer is 28.
Answer:
1 box of pencil cost 1 dollar and 1 box of pen cost 5 dollars
