Suppose the area of square A is 15 cm² and the area of square C is 42 cm². What is the area of square B if the three squares create a right triangle?

57cm2

Step-by-step explanation:

42cm cube time 15cm cube

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
