Answer:
Width = 10 and Length = 16
Step-by-step explanation:
→ Assign variables to the length and width
width = x so length = 6 + x
→ Make an equation
x + 6 + x + x + 6 + x = 52
→ Simplify
4x + 12 = 52
→ Minus 12 from both sides
4x = 40
→ Divide both sides by 10
x = 10
→ Resubstitute into the previously assigned values
width = 10 so length = 16
Answer: A. profit of $4500
<u>Step-by-step explanation:</u>
r(x) = x² + 6x + 10
- <u>c(x) = x² - 4x + 5</u>
(r - c)(x) = 10x + 5
(r - c)(4) = 10(4) + 5
= 40 + 5
= 45
(r - c)(x) represents the profit (in hundreds of dollars) in x months
(r - c)(4) represents the profit (in hundreds of dollars) in 4 months
So, the new store will have a profit of $4500 in 4 months
It’s c since the line goes down 5 and the y intercept is 3 so it would be y=-5x+3
