Area = length × width
Joseph: 12 × 9 = 108 feet
Alana: 25 × 7 = 175 feet
175 feet - 108 feet = 67 feet

Step-by-step explanation:
7.7+0.94+13=21.64
Answer:
3,000
Step-by-step explanation:
Create 2 expressions to represent the cost and the revenue, where x is the number of newspapers:
2x + 15,000 will represent the cost
5x + 6,000 will represent the revenue
Set the expressions equal to each other and solve for x:
2x + 15,000 = 5x + 6,000
15,000 = 3x + 6,000
9,000 = 3x
3,000 = x
So, 3,000 newspaper copies have to be sold to break even
Answer:
r = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)
m = 
, that is
= ( cross- multiply )
7(r + 3) = 7 ( divide both sides by 7 )
r + 3 = 1 ( subtract 3 from both sides )
r = - 2
