<h2>Hello!</h2>
The answer is:
The missing step is the step shown in the last option:
D.
To find which is the missing step, we need to remember that to cancel a square root, we need to elevate it, so:
Starting from the last step before the missing step, we have:
In order to calculate the value of the variable (x) we need to square both sides of the equation, since squaring a root will cancel the root.
We must remember the following properties:
Now, finding the missing step, we need to find what to do in order to get the expression of the following step.
So, squaring both sides of the equation in order to cancel the square root and isolate the variable, we have:
Hence, we found the the missing step is:
D.
Have a nice day!
GCF of given monomials are
<em><u>Solution:</u></em>
<em><u>Given that we have to find the greatest common factor</u></em>
Given monomials are:
When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor
Let us first find the GCF of 20 and 8 and then find GCF of variables and then multiply them together
<em><u>GCF of 20 and 8:</u></em>
The factors of 8 are: 1, 2, 4, 8
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 4
Thus GCF is
<em><u>Therefore GCF of monomials are:</u></em>
Thus GCF of given monomials are
