Which inequality models this problem? The length of a rectangle is four times its width. If the perimeter is at most 130 centimeters, what is the greatest possible value for the width?
A. 2w + 2 • (4w) < 130 B. 2w + 2 • (4w) > 130 C. 2w + 2 • (4w) ≤ 130 D. 2w + 2 • (4w) ≥ 130
130 <_ (Less than or equal to 130) so it would be D
The length of a rectangle is five times its width. If the perimeter is at most 96 centimeters, what is the greatest possible value for the width? A. 40 cm B. 19.2 cm C. 16 cm D. 8 cm
Width = w Length = 4w Perimeter of a rectangle is 2l + 2w Perimeter for this rectangle is 2w + 2(4w) We want the perimeter to be at most 130, so we want 2w + 2(4w) < or = 130
ok cool ty
welcome.
