We should divide x^2-2 from the equation.
I will spare you from the boring steps of equation dividing.
Now getting 5x+4
Just do this like you are doing long division but instead using variables, be careful there is no x term in the second expression so you have to give it an empty space :)
Answer:
exponent: 3; base: 4
Step-by-step explanation:
An exponent is used to signify repeated multiplication. In a typeset expression is has a superscript format. The base is the value being repeatedly multiplied.
The exponent is 3.
The base is 4.
_____
In plain text, an exponent is preceded by a caret (^). If the exponent consists of more than a single constant or variable, it must be enclosed in parentheses. The above expression would be written as 4^3.
A = lw
A = (x+10)(x+2)
A = x^2+2x+10x+20
A = x^2+12x+20
Lets solve the equation and see the steps so it is easier.
x/2 - 8 = 14
Add eight to both sides of the equation to get x/2 alone.
x/2 - 8 + 8 = 14 + 8
x/2 = 22
Multiply both sides by two to get x alone.
x/2 • 2 = 22 • 2
x = 44
Now we see the steps we made. Lets look at the choices. Your answer is the third choice. I hope this helps!
