Answer:
16
Step-by-step explanation:
A square has same length on all sides.
So, 18x-20=42-13x
18x+13x=42+20
31x=62
x=62/31=2
Now you can substitute x=2 in one of the equations to find the length of the side.
18x-20 = (18*2)-20 = 36-20 = 16
The triangle that has side lengths of 7, 10, and 12 is not a right triangle. The correct answer is B. No.
The reason for this can be found in the Pythagorean theorem, which is a2 + b2 = c2 (this number 2 means square)
So, let's test this.
7*7 + 10*10 = 12*12
49+100 = 144
149 = 144
Since this is not equal, this isn't a right triangle.
