Answer:
The distance added to each dimension is 2 yards.
Step-by-step explanation:
The initial dimensions of the rectangular fence is 8 yards by 4 yards.
The initial area of the rectangular fence = area of a rectangle
area of a rectangle = length x width
So that,
The initial area of the fence = 8 x 4
= 32
The initial area of the fence is 32 square yards.
But, with the new dimensions, area = 60 square yards.
(4 + x) x (8 + x) = 60
+ 12x + 28 = 60
+ 12x - 32 = 0
(x + 14) = 0 or (x - 2) = 0
x = -14 or x =2
Thus, x = 2
The distance added to each dimension is 2 yards.
Given:
Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.
Solution:
Let the number of tulips and roses are 2x and x respectively.
According to the question,
Divide both sides by 3.
Now,
Number of tulips 
Therefore, the number of tulips is 12.
Length of the outer frame: 4+2x
width of the outer frame: 3+2x
area of the outframe: (4+2x)(3+2x)=15
expand the equation: 12+8x+6x+12x^2=15
combine like terms: 4x^2+14x-3=0

I got it right :)
72 ounces is 30% of what number ( a much bigger number since 72 is only 30% of it)
Change to math
72 = .3n (30%= .3 as a decimal)
Divide both sides by .3 (dividing by a number less than 1 will make 72 increase)
