4) A rectangle as a length which is twice its width. Which of the expressions below can be used to
express the perimeter of the rectangle? Select all
that apply.

(a) 2(x) + 2(2w)
(b)x
(c) 3x
(d) 2(x + 2x)

D.

Step-by-step explanation:

2 is it's length while in the perinthesis is x for its length plus the width which is doubled, explained by the x.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

a) 7x=7
