Answer:
3(4+n) = 12+n is an equation that could be used.
12n = 12+n
11n = 12
n= 1+1/11
Step-by-step explanation:
So I guess this would look like this originally 113/10, then as a mixed number 11 3/10
Answer:
The answer is 1,440
Step-by-step explanation:
Answer:
A = 102 cm^2
Step-by-step explanation:
This figure is a trapezoid. The area is given by
A = 1/2 (b1+b2) *h where b1 is the base and b2 is the top
b1 = 21 b2 = (6+7) and h = 6
A = 1/2 (21+13) *6
A = 1/2 (34)*6
A = 102 cm^2
