A is your answer
We can cross multiply using x/70=30%/100
Solving it we get:
100x=2100 (70 times 30)
x=21
So we get a, 21 as your answer.
I hope this helped!
P= L+W
P= Perimeter, L= Length and W=Width
Length + Width = Perimeter
So, then P(22) - W(5) = L(17)
Hope that helps.


solve for "w", to find the wind's speed rate,
so hmmm what's the plane's rate? well 420 - w = r :)

Answer:
Step-by-step explanation:
8x^3 - 12x^2 - 2x + 3
4x^2(2x - 3) - 1( 2x - 3)
(4x^2 - 1)(2x - 3)
(2x - 1)(2x + 1)(2x - 3)
