Answer:
70th term is 753
Step-by-step explanation:
a70= ?
n= 70 (nth term, term to find)
a1= -6 (first term)
d= 11 (common difference)
a70= a1 + (n - 1)d
a70= -6 + 69(11)
a70= -6 + 759
a70= 753
I'm guessing since the X makes the length of the triangle 2 more than then first one, that it does the same to the other side.
So the height would be 5 and the length 6. When you plug those into the formula A=1/2 (l×w) it makes:
A=1/2(5×6)
A=1/2 (30)
A=15 ft^2.
So the answer is H
