What is (12m+4n)+(3m+7n)

15m + 11n

Step-by-step explanation:

(12m+4n)+(3m+7n) is the same as 15m+11n because all that happened was the combination of like terms.

12m + 3m = 15m

4n + 7n = 11n

(12m+4n)+(3m+7n) = 15m+11n

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
