The length of a rectangle is three times longer than its width. the perimeter of the rectangle is 16 feet. if x represents the width of the rectangle, which equation can be used to find its value? 3x + x = 16 (3x)(x) = 16 3x + 3x + x + x = 16 3x + 3x + x = 16

x - width

3x - length

16 - perimeter

x + x + 3x + 3x - perimeter

3x+3x+x+x=16

Step-by-step explanation:

The length of a rectangle is three times longer than its width. The perimeter of the rectangle is 16 feet

LEt x represents the width of the rectangle

Length is 3 times longer than its width

so length of rectangle = 3x

Perimeter of rectangle =length + length + width + width

= 3x+3x+x+x

Given Perimeter = 16

So 3x+3x+x+x=16

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
