Base = 2 x height (b = 2h)
Area = 1/2 x base x height = 1/2 x 2h x h = h x h = h^2
Answer:
the common difference is 6.
Step-by-step explanation:
Given;
first term of an AP, a = -7
let the common difference = d
The third term is written as;
T₃ = a + 2d
The eight term is written as;
T₈ = a + 7d
The ratio of the eight term to third term = 7:1

Therefore, the common difference is 6.
Answer: -9
Step-by-step explanation: You are not doing 3(-2) to get -6. That's incorrect. What you are supposed to do is multiply the base which is 3 and then multiply it with -2 so that would 3(3) twice and don't forget the negative in front of the two so that would be -9 as the correct answer. :)
