Fist we find the legnth of the diagonal
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
c=5

now the other diagonal
11^2+5^2=c^2
121+25=c^2
146=c^2
sqrt both sides12.083
closest is B

gladu [14]

5x + 15 = 2x + 3 \\ 5x + 15 + 3 = 2x \\ 5x + 18 = 2x \\ 18 = 2x - 5x \\  - 3x = 18 \\ x =  \frac{18}{ - 3}  \\  \\ x =  - 6

<h2><u>x = (-6)</u></h2>

4. When Megan solved this system using the elimination method, she added the equations together and got the equation 4y = 16. Th

Hi there!

So, our two equations are:
2x + 3y = 20 and
-2x + y = 4

We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.

Divide 24 by 4, which is 6.

y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1

So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16. 

The solution to the system is (1,6).

I hope I helped!
