Question

Can someone help asap!?

Answer 1

Answer: = √33

a^2 x b^2= c^2 remember a^2 x (b)4^2 = (c)7^2

a^2 x 16 = 49

a^2 x 16 -16 = 49-16

a^2= 33

To leave in radical form we write down all the square numbers we know.

and see if any numbers go into this as a product but if not (4,9,16,25 etc, as even squares we leave √33

Answer 2

Explanation:

`4^(2) +x^(2) =7^(2)`

`16 + x^(2) = 49`

`x^(2) = 33`

`x = √(33)`
