Nancy made 3 different stacks of wooden blocks. the first stack was 6 blocks high, the second
stack was 3 block(s) higher than the first, and the final stack was 6 block(s) higher than the
second. in total, how many blocks did nancy use for all 3 stacks?

31 blocks

Step-by-step explanation:

first stack:6

the second stack was 3 blocks higher which equals 9

so second stack is :9

the third stack is 6 blocks higher than the second block

6+9=15

now add up all the sums and you get 31!

(2,9)

i think thats the answer i checked it on google
