Use the Pythagorean theorem.

Answer 3

Follow @jprulz . Right method.

Answer 4

Do you know the theorem?

Answer 5

Yeah but it looks confusing it would be A^2 + 225 = x + 6 ? or is that wrong ...

Answer 6

You have to square each leg and set it equal to the hypotenuse.

Answer 7

That's what I did yo

Answer 8

Very wrong.

Answer 9

x^2+15^2=(x+6)^2

Answer 10

you have to expand that. Don't forget the middle term in (x+6)^2

Answer 11

Very right.

Answer 12

wait what's the square root of 1x? and the square root of 15 is 225 which I got right and would the square root of (x+6) be 7x+36? Oh god I'm so confused lol

Answer 13

x^2 is x^2 and 15^2 is 225, but (x+6)^2 is not 7x+36.

Answer 14

Do you guys need my help?

Answer 15

Think of it as(x+6)(x+6). Don't forget to FOIL
First Inside Outside Last

Answer 16

I did foil

Answer 17

If you foil, you get x^2+6x+6x+36 which is x^2+12x+36

Answer 18

OHHHH yeah mybad I totally did that in a rush

Answer 19

I feel so dumb now ._.

Answer 20
