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!

i think it is 18

step-by-step explanation:

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
