You did not include the table.

I will use this table that I found for a problem with the same statement, and for sure this will teach how to proceed, and it might even be the same data that of your table:

Division                            Record Holder          Year             Time (h)

Men's open                      Robert Cheruiyot       2006            2.121
Women's open                 Margaret Okayo        2002            2.345
Men's wheelchair             Ernst VanDyk            2004            1.305
Women's
wheelchair                        Jean Driscoll             1994            1.523

Miles per our

Just divide the distance (26.2 miles) by the time in hours

Robert            26.2 miles / 2.121 hours = 23.372 miles / hour
Margaret        26.2 miles / 2.345 hours = 11.173 miles / hour
Ernst              26.2 miles / 1.305 hours =  20.077 miles / hour
Jean               26.2 miles / 1.523 hours = 11.203 miles / hour

A rectangle has a length of x + 5 and width of x - 3. What is the area of the rectangle? Write the answer as a polynomial in sta
goldfiish [28.3K]

Answer:

Step-by-step explanation:

Area = length * width

length: x + 3

width: x - 5

A = (x + 3)(x - 5)

Simplify (x + 3)(x - 5) using the FOIL method:

 

1. First numbers: multiply the first number of each binomial together--x*x = x%5E2

2. Outer numbers: multiply the outer number of each binomial (out of the entire expression, the number farthest to the left (x) and the number farthest to the right (-5))--x*-5 = -5x

3. Inner numbers: multiply the inner number of each binomial--3*x = 3x

4. Last numbers: multiply the last number of each binomial--3*-5 = -15

==> Now, add all of the results together and combine like terms: x%5E2+-+5x+%2B+3x+-+15 = x%5E2+-+2x+-+15

Therefore, A = x%5E2+-+2x+-+15

30w^{2}x^{3}+48w^{3}+47w^{3}+9w^{3}–20w^{3}
Simora [160]

Answer:

Given the following:

30w^2x^3+48w^3+47w^{3}+9w^{3}-20w^{3}

Like terms are those terms which have same variable to the same power.

30w^2x^3+84w^3

Take 6w^2 common from 30w^2x^3 and 84w^3

then;

we have;

6w^2(5x^3+14w)

Therefore, the simplified form of 30w^2x^3+48w^3+47w^{3}+9w^{3}-20w^{3} is 6w^2(5x^3+14w)
