The equivalent expression to given expression is 1/3.

<h3>What is Equivalent Expression?</h3>

Equivalent expressions are defined as algebraic expressions which give the same resulting expression. An algebraic expression (or) a variable expression is defined as a combination of terms by the operations such as addition, subtraction, multiplication, division.

Here, given expression

    \sqrt{2/x^2} X \sqrt{x^2/18}

=   \sqrt{2 X x^2/18x^2}

=    \sqrt{1/9}

=   1/3

Thus, the equivalent expression to given expression is 1/3.

Solve 3x + 7 &gt; -x - 9. Show each step of your work.
Kruka [31]

Answer:

x > -4

Step-by-step explanation:

Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:

3x + 7 > -x -9

3x + 7 - 7 > -x -9 -7     Subtract 7 from both sides

3x > -x -16

3x + x > -x -16 + x     add x to both sides

4x > -16

\frac{4x}{4} > \frac{-16}{4}     divide both sides by 4

x > -4

In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.

A. 5°<br>B. 35°<br>C. 31°<br>D. 7°​
MrRissso [65]

Answer:

(2x +30) and (3x -5)  (they're opposite to eachother, so they're equal)

2x + 30 = 3x - 5 (set them equal to eachother, then subtract 3x from both side)

-1x = -35 (divide both sides by -1 to isolate x)

x = 35 or B (this is your answer)

Step-by-step explanation:

I hope this helps :))
