Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping? x2(4x + 1) – 2(4x + 1) x2(4x – 1) + 2(4x – 1) 4x2

Airida [17]

Looking at <span>4x3 + x2 – 8x – 2, I see immediately that x^2 can be factored out of the first 2 terms => 4x^2(x+1)
and -2 out of the last 2 terms => -2(4x+1).

Notice how the factor (4x+1) shows up twice.

We can factor this (4x+1) out, obtaining (x^2 - 2) (4x+1). These are the desired factors, found "by grouping."

Answer:

Alice will have to pay $13.33

Ben will have to pay $23.33

Kelvin will have to pay $43.33

Step-by-step explanation:

Given that

Alice destination is 20 miles away

Ben destination is 30 miles away

Calvin destination is 40 miles away.

For a mile, taxi costs 2 dollars.

To find:

How much each person has to pay if they share the same taxi to their respective destinations?

Solution:

For the first 20 miles, the taxi will be shared by all 3 of them.

Charges for 20 miles = 20 $\times$ 2 = $40

This $40 will be shared among all 3.

Each will pay = $\frac{40}{3} = \$13.33$

Charges for Alice = $13.33

Charges for Ben = $13.33

Charges for Calvin = $13.33

For the next 10 miles, the taxi will be shared by Ben and Calvin.

Charges for 10 miles = 10 $\times$ 2 = $20

This $20 will be shared between Ben and Calvin.

Each will pay = $\frac{20}{2} = \$10$

Charges for Alice = $13.33

Charges for Ben = $13.33 + 10 = $23.33

Charges for Calvin = $13.33 + 10 = $23.33

For the next 10 miles, Calvin travels alone.

Charges for 10 miles = 10 $\times$ 2 = $20

This $20 will be paid by Calvin alone.

Charges for Alice = $13.33

Charges for Ben = $23.33

Charges for Calvin = $23.33 + 20 = $43.33

The point C at a coordinate of (-3, 4) is the center of dilation of shapes WXYZ to W'X'Y'Z'

<h3>How to determine the center of dilation?</h3>

The coordinates are given as:

W = (-4, 3) X = (-2, 3) Y = (-4, 1) Z = (-2, 1)
W' = (-6, 1) X' = (0, 1) Y' = (-6, -5) Z' = (0, -6)
A = (-5, 4) B = (-3, 6) C = (-3, 4) D = (-1, 4)

Next, we plot the points on a coordinate plane

From the plane (see attachment), we can see that the point C at a coordinate of (-3, 4) is at the center of both shapes, and it is 1 unit from WXYZ and 3 units from W'X'Y'Z'.

Hence, the point C is the center of dilation
