Answer:

$20 {x}^{2} - 43xw + 21 {w}^{2}$

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.

The answer to #1 is 0.

In order to find the answer to this one (or any of these problems, simply follow the order of operations. In the case of #1, we first want to stick the 0 in for a and then continue.

$\frac{a}{b} +\frac{a + 1}{b} +\frac{a - 1}{b}$

$\frac{0}{b} +\frac{0 + 1}{b} +\frac{0 - 1}{b}$

$\frac{1}{b} +\frac{-1}{b}$

Since these two numbers cancel, you will get the answer as 0. For the rest of these, follow the basic steps provided by your teacher in PEMDAS.
