Answer:
nope
Step-by-step explanation:
they do not have the same exponent
no matter what the number with the x is, as long as the x's have the same exponent, they can be combined...
but in this problem such is not the case, because one x is to the power of 2 and the other is to the power of 1...
so, not in this problem...
Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses.
So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:
20 is the answer.
