Answer:
5 sqrt(10) = c
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
9^2 + 13^2 = c^2
81 + 169 = c^2
250 = c^2
Take the square root of each side
sqrt(250) = c
sqrt(25) sqrt(10) = c
5 sqrt(10) = c
Answer:
Step-by-step explanation:
4x+5y=6
x=
6()-7y=-20
9-7.5y-7y=-20
-14.5y=-20
y=
5()+4x=6
x=
I believe it is b but you may have to show work for that
If it's telling you to simplify then the answer should be 3x^2.
