The area of a square is 16 square units. Since 4 V. 5 2 =16 and (–4) 2 = 16 , both 4 and –4 are square roots for 16. Explain why both square roots for 16, the area of the square, cannot be the length of each side of the square.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

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°
