Answer:
commutative property of addition
Step-by-step explanation:
commutative property of addition "a + b = b + a"
Correct Question is: Find the illegal values of b in the fraction
(2b^2 + 3b - 10)/(b^2 - 2b - 8)illegal values are those which are not a part of Domain. In this case these will be such values which will make the denominator of the fraction zero.
So setting the denominator equal to zero, we can find these values.
Thus, b=-2 and b=4 are the illegal values for this expression
Using the quadratic formula, plug a=2, b=3, and c=4 into the formula because the equation given can not be factored.
x= -3(+/-) radical (3^2-4*2*2)/2(2)
therefore, x= (-3+ radical 7 i) / 4
x= (-3- radical 7 i )/ 4.
the answer choice is 1.

That's just the distance between 2 points
the distance between (x1,y1) and (x2,y2) is

we can find the distance between S and Q or P and R
S and Q is (0,0) and (a,b)


distance between P and R is between(0,b) and (a,0)




so the lengths of diagonals are congruent
