Replacing x by 4 and y by 2, it is found that the value of the expression is of 8.

The expression given is:

x(x - y) - y(y^2 - x)

We want to evaluate it for x=4 and y=2, hence, we replace x by 4 and y by 2, then:

4(4 - 2) - 2(2^2 - 4) = 4(2) - 2(0) = 8

The value of the expression is of 8.

Someone help please :(
Hunter-Best [27]

Answer:

Answers in step-by-step.

Step-by-step explanation:

We are going to make Sarah the variable "s."

Using the given information, the following equation is derived to calculate Sarah's distance.

  • S=2n-5

And the following equation will be used to calculate what Sarah collected using "p" for pledged money.

  • P=18S

If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.

  • P=18S
  • 450=18S
  • 450/18=S
  • 25 miles = S

Using Sarah's distance, we can calculate Semir's either the first equation.

  • S=2n-5
  • 25=2n-5
  • 30=2n
  • 15=n
  • Semir walked 15 miles.

We already found Sarah's distance to be 25 miles.

Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.

  • 450-72=$378

His formula is the same as Sarah's, but we'll use SS for his variable.

  • P=18SS
  • 378 = 18SS
  • 378/18=SS
  • 21= SS
  • SungSo walked 21 miles.
