ANSWER and EXPLANATION
We want to order the functions from widest to narrowest:

To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:

Hence, its table is:
For the second function:

Hence, its table is:
For the third function:

Hence, its table is:
Now, let us plot the graphs of the functions:
Therefore, from the graph, we see that the order of the functions from widest to narrowest is:
Answer:
x = 51
Step-by-step explanation:
3 x 51 = 153, 153 + 2 = 155, 155 / 5 = 31
The first polynomial is 
The other polynomial is 
Now to add polynomials we must add or subtract like terms
Adding them we have


Here 
So we add then
We get

The addition of the polynomial is 
100 cm= 1 meter 1,000 cm=meter
——————-
750 mm = 0.75 m
45 cm = 0.45 m
2.3 m
——————
Add and you should get 3.5. The tinsel is 3.5 meters long.
Answer:
a is 15, b is 15, c is -15, and d is -15 also
Step-by-step explanation:
The 2 parallel lines that surround the number are called "absolute value signs" everything inside them has an outcome of a positive number and in this case the number is 15. Like I said the number(s) inside the absolute value signs have to have a outcome of a positive number, notice in c and d there is a negative sign outside the absolute value signs. Therefore you multiply the negative seperately so, 15(-1) is -15.
