Peter made 3 different stacks of wooden blocks. The first stack was 4 blocks high, the second stack was 9 block(s) higher than the first, and the final stack
was 4 block(s) higher than the second. In total, how many blocks did Peter use
for all 3 stacks? *

We can go step by step for this problem by listing out how many blocks for each stack.

Stack 1: 4

Stack 2: 4+9=13

Stack 3: 13+4=17

Now we can sum up the number of blocks in each stack to get 4+13+17=34. The answer is 34.

f(x) = y

f(-3) = -5

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
