Answer:
14
Step-by-step explanation:
i dont know. just trust me
4is thex the yintercept is -8
For this question you have to solve the equation backwards.
A = 1/2 x (b1 + b2) x h
In order to get rid of the 1/2 (since it's division) multiply each side by 2
now we have: 2A = (b1 + b2) x h
Now do the same to the get rid of the (b1 + b2) (divide each side by it)
2A/(b1 + b2) = h
Only in d. are the number related by multiplication (Multiplied by 3 each time to get the next number in the sequence).
3 x 3 =9
9 x 3 =27
27 x 3 = 81 etc.
