You can simplify expressions by simplifying parentheses by using the distributive property and combing like terms.
Combining like terms is the process of adding up numbers with the same variable(s) and exponent. If a term does not have an exponent then an exponent of 1 is implied.
There is no parentheses in the expression 3a + 7 - a - 7
But, there are like terms in the expression.
Which are the like terms?
3a and a are both like terms. They both have the same variables and they both have the same exponent.
7 and -7 are like terms, too.
3a + 7 - a - 7
2a
So, 2a is the simplified version.

Answer:
D
Step-by-step explanation:
Volume for a sphere: 4/3(pi)r^3
4/3(pi)(1x1x1)= 4/3pi
hope this helped :)
E^(∞): This is defined as 'e' being raised to a huge value. Hence the result will definitely be a large number which is also infinity (∞), i.e. e^(∞) = ∞.
e^(- ∞) = 1/e^(∞) = 1/∞ = 0.
Answer:
A.
Step-by-step explanation:
We are given that
A region: It includes all element of p but not q.
B region: It includes elements of p and q.It is represented by
.
C region: it contained the elements of q only.
Union of A , B and C are represented by

Hence, the region A,B and C represents by

Option A is true.
