Question

The length of a rectangle is 12x inches and the width is 15 inches. the area is 2916 inches.

Answer 1

The equation is 2916= 12x • 15, since area is length times width.
in this case, x would be 16.2
first, you divide 15 on both sides, then, you isolate x by dividing by 12 on both sides. the answer is 16.2
hope this helps
