Jess made 3 different stacks of wooden blocks. the first stack was 8 blocks high ,the second stack was 4 blocks higher than the first, and the final was 8 blocks higher than the second. in total, how many blocks did jess use for all 3 stacks

Jess used 40 blocks in total.

Step-by-step explanation:

First stack: 8 blocks

Second stack: First stack + 4 = 8 + 4 = 12 blocks

Third stack: Second stack + 8 = 12 + 8 = 20 blocks

Total number of blocks: First stack + Second stack + Third stack = 8 + 12 + 20 = 40 blocks

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

answer: the correct answer is -32
