The left side of this equation is already a perfect square: <span>x^2-10x+25=35.
Rewriting it, we get (x-5)^2 = 35.
Taking the sqrt of both sides, x-5 = sqrt(35).
Solving for x: x = 5 plus or minus sqrt(35) (answers)</span>
First we have to know the Pythagoreans theorem which is
a^2+b^2=c^2
7^2+8^2=c^2
49+64= 10.63
Hope this helps
So in order to tell if something makes a right triangle we would use the formula Pythagorean theorem.a^2+b^2=c^2 and it must be equal and the same if not then those sides cant be use to make a right triangle
5^2+6^2=7^2
25+36=49
61=49
No ! False
Answer:
Step-by-step explanation:
all u really need to do for this is look at ur x values.....if there is no repeating x values, then it is a function. A function can have repeating y values....just not the x values
A. This is a function because there is no repeating x values
B. not a function....u have repeating x values of -1
C. not a function...u have repeating x values of 3
D. not a function...u have repeating x values of -1
