How to get a perfect square?</h3>
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:

To write 4 in in scientific notation:

Then the operation:

Gives a square number.

Answer:
x = 18
Step-by-step explanation:
The scale factor between the two numerators are 1/2.
Scale factor
= numeratorANS / numeratorKNOWN
= 7/14
= 1/2
Multiply the denominator by the scale factor to find x.
x = 36 * 1/2
x = 18
Answer:
Move all terms that don't contain x to the right side and solve.
x=−1 − 4y/3
Move all terms that don't contain x to the right side and solve.
x=6/5 − 3y/5
