(2v-7x)^2=
(2v-7x)(2v-7x) Next step, FOIL.
2v^2-14vx-14vx+49x^2
2v^2-28vx+49x^2

Not sure how you're going to want to re-write that, but that should be the basic answer

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 4343 states. what is the probability that
QveST [7]

If the 4 states have to be in a specific order say ABCD, then the total number of different possible routes is:

 43P4 = 2,961,840

So the probability is:

1 / 2,961,840 = 3.38 x 10^-7

 

But if the 4 states can be in any order such as DBAC, ACBD etc, then the total number of different possible routes is:

 43C4 = 123,410

So the probability is:

1 / 123,410 = 8.1 x 10^-6

 

No I don’t think it is practical to list all the different possible routes to select the one that is best. We can simply use mathematical models to solve for that one.

Hamburger Heaven is having a lunch special where customers buy one 1/4 pound cheeseburger and get one free. If they set aside 11
Sloan [31]

Answer: 459 cheeseburgers

Step-by-step explanation:

To find out the number of cheeseburgers that can be made, divide the amount of meat set aside by the amount of meat it takes to make one cheeseburger.

The amount of meat they have is:

= 114²/₃

= 344/3

Number of cheeseburgers is:

= 344/3 ÷ 1/4

= 344/3 * 4/1

= 1,376 / 3

= 458.67

= 459 cheeseburgers

Given polynomials p, q, r, and s . q≠0 ,s≠0 and r≠0
kkurt [141]

Answer:

\frac{p}{q} \div \frac{r}{s} = \frac{ps}{qr}

Step-by-step explanation:

Given

\frac{p}{q} \div \frac{r}{s} =

Required

Solve

\frac{p}{q} \div \frac{r}{s} =

Turn division to multiplication

\frac{p}{q} \div \frac{r}{s} = \frac{p}{q} * \frac{s}{r}

\frac{p}{q} \div \frac{r}{s} = \frac{ps}{qr}
