Use the rectangle to answer the question. 12 millimeters
9 millimeters
What is the area of the rectangle?
O A 21 square millimeters
OB. 42 square millimeters
O c. 81 square millimeters
OD. 108 square millimeters
ОЕ.
144 square millimeters

12 x 9 = 108

Step-by-step explanation:

Just multiply the 2 given lengths when finding AREA of a rectangle.

answer: i think it is (1,-2)

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°
