The area of a trapezoid is the height times the average of the two bases, mathematically:
A=h(b1+b2)/2, in this case h=6in, b1=9in, and b2=7in so
A=6(9+7)/2
A=6*16/2
A=48in^2
1. 3 1/4
2.9 1/2 hope it helped
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).
The function is increasing on (-3,1).
No local or absolute minimum.
(1,4) is an absolute max.
Answer:
angle c is congruent to angle D.
Step-by-step explanation:
IF YOUR SOLVING FOR A THE ANSWER WOULD BE A=X+12
IF YOUR SOLVING FOR X IT WOULD BE X=-12+A
