A rectangle has a perimeter of 84 meters. One dimension is 7 meters. How long is the unknown dimension?

The unknown dimension is 35

Step-by-step explanation:

The perimeter of a rectangle is l+l+w+w or 2l+2w (l=length, w=width)

then we subtract 14 from 84

Let's check our answer

Hope this helps :-)

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°

you'll have to attache the image of the bar graph in order for us to answer : )
