The perimeter of the rectangle is unknown. the length is x + 4 ft, while the width is 2x ft. the area is unknown. what is the perimeter?

6x + 8 feet.

Step-by-step explanation:

The perimeter of a rectangle is equal to two times the height, plus two times the base. In this case, one side is given as x + 4 feet, and the other as 2x feet.

So, simply multiply each side by two, and add them together.

(2)(x + 4) + (2)(2x)

2x + 8 + 4x = 6x + 8 feet

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.
