Answer:
Step-by-step explanation:
That is correct.
P=4s=4(12)=48in
A=s^2=12^2=144in^2
Answer:
The first option: A.) For any numbers a, b, and c, a(b + c) = ab + ac.
Step-by-step explanation:
So anytime that you have a number or letter in front of a set of parenthesis that has numbers within (such as the example problem of: a(b + c)), you need to take the number outside of the parenthesis (a) in this situation) and multiply it to all of the numbers inside the parenthesis, like this:
a(b + c).
Multiply a into b, then multiply a into c, so that the equation looks like this:
ab + ac.
I hope that this helps.
To solve this problem you must apply the proccedure shown below:
a) You must sum terms with same exponents, therefore, you have that the sum of these two polynomials is:
b) First, you must mulitply the signs of the second polynomial by the negative sign, and them, you apply an algebraic sum. Therefore, the result is:
The answers are: a); b)
