Answer:
Rise (y) over Run (x)
12-5
------
3-1
7/2=m
Step-by-step explanation:
Width = x
length = x+10
Area of deck = 144 square feet
Area = length * width
144 = x(x+10)
Solving for x in a quadratic:
x²+10x = 144
x²+10x-144 = 0
Factor:
(x+18)(x-8) = 0
Solving for x:
x = 8, x = -18
Dimensions cannot be negative, therefore x = 8, only.
Length = x + 10
Length = 18
Width = 8
The ratio of dates to peanuts is the same as cashews to raisins. Simplified, both ratios equal 1/2.
