The statement Which can be represented by the expression 17 – 2x is the difference between 17 and twice a number x, the correct option is C.
Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that;
The expression= 17-2x
Now,
The expression 17 - 2x represents;
the difference between 17
and 2x is twice a number x.
Therefore, the answer of the given expression will be the difference between 17 and twice a number x.

Answer:
3.3
Step-by-step explanation:
7-7=0
-3+-7=-10
10 divided by 3 is 3.3
b. They are opposites, but not parallel.
c. They are opposites and parallel.
d. They are equal, but not parallel.
Answer: Option a
They are equal and parallel
Step-by-step explanation:
If a and b have the same direction then necessarily a and b are parallel.
We know that they also have the same magnitude.
Two vectors are equal if they have the same magnitude and direction.
Then we can say that a and b are equal and we can also say that they are parallel.
Therefore the correct option is the option a

Answer:
Step-by-step explanation:
The volume of a rectanguiar shape like this one is V = L * W * H, where the letters represent Length, Width and Height. Here L is the longest dimension and is 28 - 2x; W is the width and is 22-2x; and finally, x is the height. Thus, the volume of this box must be
V(x) = (28 - 2x)*(22 - 2x)*x
and we want to maximize V(x).
One way of doing that is to graph V(x) and look for any local maximum of the graph. We'd want to determine the value of x for which V(x) is a maximum.
Another way, for those who know some calculus, is to use the first and second derivatives to identify the value of x at which V is at a maximum.

Answer: The required product is
Step-by-step explanation: We are to find the product f the following two algebraic expressions:
To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.
The multiplication is as follows:
Thus, the required product is
Answer:
Step-by-step explanation:
Given expressions are 2x+ y and 5x -y +3
Product of 2x+y and 5x-y+3 is
( by applying distributive property under multiplication over addition)
⇒ (again by distributive property)
⇒ ( by operating the like terms.)
