Answer:
x^2 -10x+25
Step-by-step explanation:
(x-5)^2
Rewriting
(x-5)(x-5)
FOIL
first: x*x = x^2
outer: x* -5 = -5x
inner: -5*x = -5x
last: -5 * -5 = +25
Add them together
x^2 -5x-5x+25
Combine
x^2 -10x+25

Answer: 1 pound of cheese cost $4.2
Step-by-step explanation:
Nola purchased 2.5 pounds of cheese for 10. $50
Her mother purchased 3 pounds of the same cheese for $12.60
If the cost of the cheese varies directly with the number of pounds purchased, it means that the higher the pounds of cheese purchased, the higher the cost
To determine the the cost of 1 pound of cheese, we wound divide the the cheese by the number of pounds bought.
It becomes 10.5/2.5 = 4.2
<h3>Henry drove the truck for 208 miles</h3>
<em><u>Solution:</u></em>
Given that,
Base fee = $ 18.95
Additional charge of $.79 for each mile driven
Let "x" be the miles driven
Henry had to pay $183.27 when he returned the truck
Therefore,
Cost for rent = base fee + charge for "x" miles
183.27 = 18.95 + 0.79x
0.79x = 183.27 - 18.95
0.79x = 164.32
Divide both sides by 0.79
x = 208
Thus Henry drove for 208 miles the truck
