B - (5 x 8) - 3
A is adding 3, not subtracting.
C is basically 5 squared.
D is 5 lots of 11.
Answer:
polynomial of degree 3
Step-by-step explanation:
Given
3x³ - 6x
The degree of a polynomial is given by the exponent of the term with the largest exponent.
In this case 3x³ has exponent 3 and - 6x has exponent 1
Thus this is a polynomial of degree 3
For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.
For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.
Given that total amount of metal in the beginning = 8.2 square feet
Given that used amount of metal = 2.1 square feet
Then remaining amount of metal = (8.2-2.1) = 6.1 square feet
Now it says that "$183 worth of sheet metal remaining".
That means cost of 6.1 square feet is $183.
Let cost of 1 square feet of the metal = x
Then cost of 6.1 square feet of the metal = 6.1x
Both expressions 6.1x and $183 represent the cost of the remaining metal so the required equation will be:
6.1x=183
Now we can solve it to find the solution
x=183/6.1
x=30
So the cost per square feet of the metal = $30
Hence final answer is $30 per square feet.
