Let x be the length and y be the width of a rectangle.
Area = xy
When x and y are doubled
Length = 2x and Width = 2y
Area = 2x x 2y
Area = 4xy
-------------------------------------------------------------------------------------------------
Answer: When the dimension is doubled, the area is 4 times the original.

Well you can either think of actually dividing the fraction or reduce to lowest forms which is 1/2. then from 1/2 you can either divide that or just say it is .5.
Answer= 6.5y+12
distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)
then add like terms together.
12.5y + (-6y) = 6.5y
15 + (-3) = 12
make it one expression.
6.5y + 12
The empirical rule states that approximately 68/95/99.7% of a normal distribution lies within 1/2/3 standard deviations. So the answer is 68%.
$75 a month. 75x12 = 900. i used 12 because that’s the number of months in a year. hope this helps
