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.
I believe the answer would be 2 23/42. Sorry, if I am wrong with this answer. Sorry, i also mean the answer should be actually 1 3/7

Answer:
4,784
Step-by-step explanation:
Find how many are defective
Convert 8% to a decimal
8/100=0.08
Multiply
5,200*0.08=416
416 are defective, to find how many aren't subtract the defective from the whole
5,200-416=4784
So, 4,784 are not defective
Hope this helps! :)
