Answer:
3
Step-by-step explanation:
Easy pythagorean theorum question.
The law states that "A squared plus B squared, equals C squared."
A and B are the two sides that border the 90 degree mark.
C is the hypotenuse or the longest side/diagonal.
Since we know C and A (I chose to use A because why not) we can fill in the equation with what we know
2^2 + ?^2 = ![\sqrt{13^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B13%5E%7B2%7D%20%7D)
So
4 + ?^2 = ![\sqrt{13^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B13%5E%7B2%7D%20%7D)
Since the 13 is already squared in side of a root, it stays as 13
4 + x^2 = 13
4 - 4 + x^2 = 13 - 4
x^2 = 9
x^2 root = root of 9
x = 3
The missing side is 3.
Or you could use an online calculator xD
Answer:
x < -2; x > 5
Step-by-step explanation:
5x + 7 < - 3 3x - 4 > 11
-7 -7 +4 +4
5x < - 10 3x > 15
/ 5 /5 /3 /3
x < -2 x > 5
Answer:
-27/5
Step-by-step explanation:
[x*4 + 3(x-1)]\12=2+x
4x+ 3x -3 =12(2+x)
7x -3 =24 +12x
7x-12x =24 +3
-5x =27
x = (-27/5)
