A picture is 5 inches by 7 inches. There is a frame around the picture that is of uniform width. The area of the frame and the picture combined is 72 in? How wide is the picture frame?
Formulate an equation that you would use to solve for x, the width of the picture frame.
es :)
A)
(5 + x)(7 + x) = 72
B)
(5 - x)(7 - x) = 72
C)
(5 + 2x)(7 + 2x) = 72
D)
(5 - 2x)(7 - 2x) = 72

3; 9 is 8 to -4

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
