The answer is 6 that's how many places its away from zero.
Answer:

Step-by-step explanation:
In the equation: 
x's can be simplified and y's can be simplified!
Always remember that for exponents, you subtract the powers when dividing
so for x: 15-8 = 7
for y: 9-3 = 6
so the final answer is: 
2x2-3x-20=0
4-3x-20=0
2-20=-16
-3x-16=0
-3x=16
x= -5.33333
I think i did it right. i hope this helps.
B = 26in, c = 40in
a^2 = 26^2 + 40^2
= 2276 (square root it)
a = 2root569 // 47.7in
1. C never. never because isosceles triangles are similar if a base angle of one is congruent to a base angle of another.
2.A AAA Similarity Postulate. An equilateral triangle is equal on each side, also AAA Similarity Postulate is were it is all equal all around
I hope this helped!
