the combined area of two squares is 45 square cm. Each side of one square is twice as long as the side of the other Square. What

Vlad1618 [11]

Answer:

L=6 cm l=3

Step-by-step explanation:

x+y=45

L=2l

Big Square Area

L*L=x

Little Square

l*l=y

Substituting

(L*L)+(l*l)=45

(2l*2l)+(l*l)=45

(4l^2)+(l^2)=45

5l^2=45

l^2=45/5

l^2=9

l=sqrt(9)

l=3

L=2(3)

L=6

Please explain this problem. I don't know what its asking, or what to do.

The answers are x=4 and y=323/2

1) 40/2x-3=8

Multiply both sides by 2x-3 to get rid of fraction

40= 8(2x-3)

Distribute 8

40= 16x-24

Add 24 to both sides

64=16x

Divide by 16

4=x

2) 2y-3/40=8

Multiply both sides by 40 to red rod of fraction

2y-3=320

Add 3 to both sides

2y= 323

Divide by 2

Y=323/2

Now just describe the differences in solving them

FYI / means fraction, right after the slash is bottom of fraction

This is because the first time there are 2 green marbles and ten marbles total but the second time he had already taken out a green marble so there is only 1 green marble left and 9 marbles total.
Hope this helps :)
