HELPP IS VERY MUCH NEEDED

Since this is a right triangle, we can use the Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 147

b = sqrt(147) = 7 sqrt(3) miles

Hope this helps!

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
