Answer:
Width is 14 ft, length is 28 ft
Step-by-step explanation:
We know that the length is twice as long as the width. This can be represented by L=2W.
The equation to solve this is 84=W+W+L+L. We can replace both the L variables with 2W, since that is what L equals.
84=W+W+2W+2W. We simplifiy to get 84=6W. We divide 84 by 6 and get W=14.
Now that we know the width, finding the length is easier. L=2(14). L=28 ft.
To check our math we can do 28+28+14+14. 56+28=84 ft.
Therefore, the width is 14 ft and the length is 28 ft.
35 : 10 = 7*5 : 2*5 = 7 : 2
Thus 35 : 10 = 7 : 2;
but 35:10 ≠ 7:5
269.99(0.15) = 40.4985
269.99 - = 229.4915
rounded to 229.49
so the discounted price is
$229.49
The associative property of multiplication states that (a × b) × c= a × (b × c).
(4 x 8) x 3 = (8 x 4) x 3 is an example of the associative property of multiplication.
