Given:

The shown represents the difference between the squares
So, the product of the polynomials will be as follows:

So, the answer will be:
This simplifies to:

The degree of our simplified answer is 4
Answer:
The total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .
Step-by-step explanation:
As given
Sue buys 5 pieces of fabric.

i.e



In the decimal form
Total length of fabric sue buys = 8.5 yards
As given
One yard of the fabric costs $5

= $ 42.5
Therefore the total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .
So will be choice D.
bc. 5/6 = 10/12 = 2*5/2*6 = 5/6
Answer: B
Step-by-step explanation:
To find the inverse function, you switch x with y and y with x. Then, you solve for y.
[switch x with y, and y with x]
[add both sides by 4]
[square root both sides]
[add both sides by 1]

Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.
Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
