Remember difference of 2 perfect squares?
we do the same for denom, to get the √5 to 5

1-√5 times 1+√5=1-5


so what we do is
(6-√5)/(1-√5) times (1+√5)/(1+√5)=
(1+5√5)/(1-5)=
(1+5√5)/-4=
(-1-5√5)/4

4. You work in the upholstery department of a furniture factory.
Wewaii [24]

Answer:

a. $1360

b. $8.50 per hour

Step-by-step explanation:

a.

5 couches upholstered, each 105 equals 5 * 105 = 525

6 loveseats upholstered, each 85 equals 6 * 85 = 510

5 chairs upholstered, each 65 equals 5 * 65 = 325

Hence, total pay = 525 + 510 + 325 = $1360

b.

To find hourly rate, we take total amount and divide it by number of hours.

1360/160 = $8.5 per hour

Hence, hourly rate is $8.50 per hour

Which graph can be used to find the solution(s) to x2 – 4x + 4 = 2x + 1 + x2?
deff fn [24]

The solution to the equation x² – 4x + 4 = 2x + 1 + x² is x = 2.5 and the graph is shown in the picture.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have an equation:

x² – 4x + 4 = 2x + 1 + x²

After solving:

-4x + 4 = 2x + 1

6x = 3

x = 1/2 = 0.5

Thus, the solution to the equation x² – 4x + 4 = 2x + 1 + x² is x = 2.5 and the graph is shown in the picture.
