Find the volume of the right triangular prism. A) 120 cubic centimeters

B) 90 cubic centimeters

C) 60 cubic centimeters

D) 150 cubic centimeters

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

the answer is 21%.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
