Question

The expression 16x2 +40x+25 represents the area of a square rooftop. Write an expression that represents the perimeter of the rooftop?

Step-by-step explanation:

Find the lenght with the inverse formula.

If A = l²

l = √A

then you find the perimeter multipling l * 4

your expression is:

4 * √(16x2 +40x+25)

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°
