In the diagram on the right, each of the squares touches adjacent squares at the corners and the line GH along one of the edges. If the length of GH is 24cm, what is the total perimeter of all the squares?

96cm

Step-by-step explanation:

If we had the side lengths, we'd multiply the side length of each square by 4 to find its perimeter. So, the total perimeter can be found by multiplying 24 by 4.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
