We can actually see that the statements that are true are:
A. x = 1 is a solution.
C. x = –1 is a solution.
<h3>What is rational equation?</h3>
Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.
We can see then that:
It's clear that: x ≠ 0 and x ≠ -6.
Looking for the LCM of the left hand side, we will have:
So, we will see that left hand side and right hand side are equal.
or
So, we can see that options A and C are correct.

The answer is A. 16 edges
Euler's polyhedron formula:
f + v - e = 2
f - the number of faces
v - the number of vertices
<span>e - the number of edges
</span>
f = 5 congruent <span>squares + 4 congruent equilateral triangles = 9
v = 9
e = ?
f + v - e = 2
e = f + v - 2
e = 9 + 9 - 2
e = 16</span>
Answer:
(2x-3) (2x+3)
zeros, x intercepts: -3/2, 3/2
Step-by-step explanation:
4x^2 -9
We know the difference of squares is a^2 -b^2
This factors into (a-b) (a+b)
Let 4x^2 =a^2
Taking the square root
2x =a
Let b^2 =9
Taking the square root
b= 3
(4x^2-9 ) = (2x-3) (2x+3)
To find the zeros, we set the equation equal to zero
(4x^2-9 ) = (2x-3) (2x+3) =0
Using the zero product property
2x-3 =0 and 2x+3 =0
2x-3+3 = 0+3 2x+3-3 = 0-3
2x=3 2x=-3
Divide by 2
2x/2 = 3/2 2x/2 = -3/2
x = 3/2 x = -3/2
These are the zeros of the equation (which are also the x intercepts)

Step-by-step explanation:
fair coin is two sided Head H and Tail T
thrown 3 times
number of sample space n(s)=2³=>8
sample space (s)={HHH,HHT,HTH,HTT,THH,TTH,THT,TTT}
no of a head and two tails= 3/8
