The length and width of a rectangle are 1/6 inches and 3/8 inches. What is the perimeter (in inches) of the rectangle?

1 1/12inches

Step-by-step explanation:

Given

Length = 1/6 inches

Width = 3/8 inches

Perimeter of the rectangle = 2 (Length + Width)

substitute

P = 2(1/6 + 3/8)

P = 2(4+9/24)

P=  2(13/24)

P = 26/24

P = 1 2/24

P = 1 1/12inches

hence the perimeter of the triangle is 1 1/12inches

1.55x - 2.16

Step-by-step explanation:

To simplify the expression, we expand the brackets while taking note of the signs:

0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2)

(0.2 * 5x) + (0.2 * -0.3) + (-0.5 * -1.1x) + (-0.5 * 4.2)

x - 0.06 + 0.55x - 2.1

Collect like terms:

x + 0.55x - 0.06 - 2.1

=> 1.55x - 2.16

This is the simplified expression.
