Hello from MrBillDoesMath!
Answer:
1/ 91.4
Discussion:
Evaluate 1/ ( 3x^3 + 5.2y) when x = 3, y = 2.
1/ (3 (3)^3 + 5.2(2)) =
1/ ( 3 * 27 + 10.4) =
1/ ( 81 + 10.4) =
1/ (91.4) =
.0109 (approx)
Thank you,
MrB
Answer:
You can also work on the ways that you write polynomials. One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.
Step-by-step explanation:
Write the expression 3x−8+4x5 in standard form.
First, look at the degrees for each term in the expression.
3x has a degree of 1
8 has a degree of 0
4x5 has a degree of 5
Next, write this trinomial in order by degree, highest to lowest
4x5+3x−8
The answer is 4x5+3x−8.
The degree of a polynomial is the same as the degree of the highest term, so this expression is called a fifth degree trinomial.

The answer is below
Step-by-step explanation:
An equation shows the relationship between two or more variables. An equation is a statement that shows the equality between expressions. An equation with infinitely many solution is when all numbers are solutions, that is there is no one solution. Example is: x + 3 = x + 3.
When each side of an equation has been simplified, equations that have the same coefficients and the same constants on each side have infinitely many solutions
Given: Shandra can do the complete work in 45 minutes.
So, Shandra's 1-minute work = 1 / 45 and
Kelly can do the same complete work in 1 hour and 15 minutes = 75 minutes.
So, Kelly's 1-minute work = 1 / 75
Now, we shall calculate Shandra's and Kelly's 1-minute work
By both 1 minute work = (1/45) + (1 / 75) = 8 / 225
∵ 8 /225 Parts can be completed by both = in 1 minute
∴ Complete work (1) can be completed by both = 225 / 8 minutes
or, = in 28 minutes and 7.5 second
Hence, the assumption taken by both was incorrect.
The best described time will be 28 minutes and 8 seconds.
