Answer:

$5 \sqrt{3} - 20 \sqrt{2}$

Step-by-step explanation:

$simpify \\ \sqrt{75} - 4 \sqrt{8} - 3 \sqrt{32} \\ from \: the \: above \: get \: two \: numbers \: \\ such \: that \: when \: multiplied \: gives \\ \: the \: numbers \: inside \: the \: root \\ and \: one \: of \: the \: numers \: should \\ be \: a \: perfect \: square. \\ \sqrt{25 \times 3} - 4 \sqrt{4 \times 2} - 3\sqrt{16 \times 2} \\ 5 \sqrt{3} - 4 \times 2 \sqrt{2} -3 \times 4\sqrt{2} \\ 5 \sqrt{3} - 8 \sqrt{2} - 12\sqrt{2} \\ 5 \sqrt{3} - 20 \sqrt{2}$

For the equations given below, which statement is true?

Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

Step-by-step explanation:

You know that the first equation is:

$-3x-8=19$

And the second equation is:

$-3x-2=25$

According to the Addition property of equality:

If $a=b$ ; then $a+c=b+c$

Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:

$-3x-8=19\\\\-3x-8+(6)=19+(6)$

$-3x-2=25$

Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.

If you want to verify this, you can solve for "x" from both equations:

- First equation:

$-3x-8=19\\\\-3x=19+8\\\\x=\frac{27}{-3}\\\\x=-9$
