Answer:

Final answer is C. $(2x-5)(2x-5)$ .

Step-by-step explanation:

Given expression is $4x^2-20x+25$ .

We can factor that by splitting middle term into two parts then do grouping as shown below:

$4x^2-20x+25$

$=4x^2-10x-10x+25$

$=2x(2x-5)-5(2x-5)$

$=(2x-5)(2x-5)$

Which correctly matches with choice C. $(2x-5)(2x-5)$ .

Hence final answer is C. $(2x-5)(2x-5)$ .

Ann went on a trip. His room cost $115.62 each night. His flight cost $45.70 and his flight home was $32.49. He averaged $15.00

Allushta [10]

His room was 115.62 per night and he stayed 3 nights so that is
115.62 * 3 = 346.86

his flight was 45.70 + 32.49 there and home so
45.70 + 32.49 = 78.19

15.00 a day on food for 4 days is
15.00 * 4 = 60

she won 75 and lost 15 so
75 - 15 = 60

add them up
346.86 + 78.19 + 60 + 60 = 545.05

Sam needs to make a long-distance call from a pay phone. With his prepaid phone card, he will be charged $1.00 to connect and $0

Mademuasel [1]

Answer: The required system of equations representing the given situation is

$y=1+0.5x\\\\y=3+0.25x$

Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.

We are to write a system to represent the situation.

Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.

According to the given information,

with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.

So, the equation representing this situation is

$y=1+0.5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.

So, the equation representing this situation is

$y=3+0.25x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)$

Thus, the required system of equations representing the given situation is

$y=1+0.5x\\\\y=3+0.25x$

Sergio [31]

We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation $y=35795(0.83)^x$ , where x represents the number of years since purchase and y represents the value (in dollars) of the car.
