Multiply (4x-3w)(5x-7w)
andre [41]

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.

Use the formula A = P(1 + r)" to solve.
Llana [10]

Answer:

Rate = 0.45 or 45%.

Step-by-step explanation:

20184 = 9600(1 + r)^2

(1 + r)^2 = 20184/9600 = 2.1025

Taking square roots of both sides:

1 + r = 1.45

r = 1.45 - 1 = 0.45.

n the right triangular prism below, BG FC The volume of the prism is 900 cubic centimeters. The height of the prism is 15 centim
Bad White [126]
12 cm

Remember, V=Bh

-I think I did the process incorrectly but this is what I did:
900=(10)(15)
900=150 (divide 150 on both sides)
you get 6 but then I multiplied by 2 and got 12.
The answer 12 is correct though so I hope this helped! and if someone could explain the process better that would be great lol.
