If I'm understanding the question right:
12) 24 x 10^4
13) 93,000,000
Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.
Answer:
x = -3,0,3
Step-by-step explanation:
5x^3 – 45x = 0
Factor out 5x
5x( x^2 - 9) =0
Factor inside the parentheses which is the difference of squares
a^2 - b^2 = (a-b)(a+b)
5x( x-3)(x+3) =0
Using the zero product property
5x =0 x-3=0 x+3 =0
x=0 x=3 x=-3
x = -3,0,3
So of you set it equal to each other
150m+3m = 9m
-3m = -3m
you get 150m=6m
and you divide by 6 on each side so it comes out to 25 minutes... I think...
