solution,

(4x - 3w)(5x - 7w) \\  = 4x(5x - 7w) - 3w(5x - 7w) \\  = 20 {x}^{2}  - 28xw - 15xw + 21 {w}^{2}  \\  = 20 {x}^{2}  - 43xw + 21 {w}^{2}

Hope this helps...

Good luck on your assignment..

Answer:

20x² - 43xw + 21w²

Step-by-step explanation:

We use FOIL to expand the expression:

F - First

4x(5x) = 20x²

O - Outside

4x(-7w) = -28xw

I - Inside

-3w(5x) = -15xw

L - Last

-3w(-7w) = 21w²

20x² - 28xw - 15xw + 21w²

Combine like terms and add up using correct signs and you should get your answer.

There were 296296 tickets purchased for a major league baseball game. The general admissiongeneral admission tickets cost ​$6.50
VMariaS [17]

Answer:

The general admission ticket number is 160 and the upper box ticket number is 136

Step-by-step explanation:

In this case we can solve it using a 2x2 system of equations, like this:

let x be general admission tickets number

let y be upper box tickets  number

So:

6.5 * x + 10 * y = 2400

x + y = 296 => x = 296 - y

Replacing, we are left with that:

6.5 * (296 - y) + 10 * y = 2400

1924 - 6.5 * y + 10 * y = 2400

10 * y - 6.5 * y = 2400 - 1924

3.5 * y = 476

y = 476 / 3.5

y = 136

Now to calculate x:

x = 296 - 136

x = 160

The general admission ticket number is 160 and the upper box ticket number is 136

A sweater is marked down from an original price of $45 to $33.75. By what percent has the original price of the sweater been mar
BlackZzzverrR [31]
<span>33.75/45.00 x 100 = 75%
This means you are paying 75% of the original.

That means that the price has been marked down by 100-75 = 25% because that is how much of the original you are NOT paying.

Therefore, the answer is 25%. </span>

Stells [14]

Answer: \dfrac14

Given: The factory produces equal quantities of four flavors cherry lemon orange and strawberry.

Let  orange candy= cherry = lemon = strawberry  = x

Total candies = x + x + x + x= 4x

The probability that a randomly selected candy is orange = \dfrac{x}{4x}=\dfrac14
