A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 10 cm long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the bookmark? Use 3.14 for π.

I don't think this is right since it is a negative number but i tried ;-; -10.2

Step-by-step explanation:

First do the area of the rectangle(bookmark) ((L x W)) = 40 ... Then do the area of the semicircle(holes) 50.27 ((extra- next cut that in half, = 25.135(optional- round to 25.1?) x2)), And subtract that number from 40. = -10.2

go on the tube you might find some information there

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
