Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x

Agata [3.3K]

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:

$\frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{x + 10}{ {x}^{3} + 6 {x}^{2} }$

It's clear that: x ≠ 0 and x ≠ -6.

Looking for the LCM of the left hand side, we will have:

$\frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{4 {x}^{2 } + (x + 6)}{(x + 6) {x}^{2} }$

So, we will see that left hand side and right hand side are equal.

$4 {x}^{2} + x + 6 = x + 10$

$4 {x}^{2} = 10 - 6$

$4 {x}^{2} = 4$

${x}^{2} = 1$

$x = 1$

$x = - 1$

So, we can see that options A and C are correct.

95% of 160 I need help with this question

Pani-rosa [81]

You can write it several ways. Here are two:

1) Proportion
160/1.00=x/0.95
(160 is the whole, 1.00 or 100%, and x is 95% of the whole. Solve for x.)
x=160*0.95 = 152/1 = 152
 1.00

2) Simple multiplication expression
"of" in math almost always means "multiply"
95% becomes 0.95. Multiply 0.95 by 160 to get your answer.
0.95*160=152

Either way, you get 152, so that is your final answer.
