Answer:

(x-2y-8)(x-2y-4)

Step-by-step explanation:

Let (x-2y) = x

x^2 -12x +32

Then factor the quadratic polynomial by 2 brackets factoring.

(x-8)(x-4)

Then convert x to (x-2y)

(x-2y-8)(x-2y-4)

Answer:

359.2 cubic inches

Step-by-step explanation:

Answer:

w = -2

Step-by-step explanation:

(5w - 8)/3 = 4w + 2

First, we will distribute the division problem on the left.

5w/3 - 8/3 = 4w + 2

Next, subtract 4w from both sides

5w/3 - 8/3 - 4w = 4w + 2 - 4w

We have to turn 4w on the left side into a fraction, but we have to make sure they are like fractions (meaning they have the same denominator).

5w/3 - 8/3 - 12w/3 = 2

5w/3 and -12w/3 are like terms (same variables) so we will subtract -12w/3 from 5w/3

-7w/3 - 8/3 = 2

Now, we will add 8/3 to both sides

-7w/3 - 8/3 + 8/3 = 2 + 8/3

to add 2 and 8/3 together, we need to make them like fractions

-7w/3 = 6/3 + 8/3

-7w/3 = 14/3

Now we get rid of the 3 by mutliplying 3 to both sides

3 * (-7w/3) = 3 * (14/3)

-7w = 14

No we have to divide -7 to both sides

-7w/-7 = 14/-7

w = -2

the next one is d(v) = 2.15v^2 / 22.54

Step-by-step explanation:

i just did this assignment. also thanks to the answer above me :)

We have that the value of f, rounded to the nearest hundredth.

f_1=0.02

f_2=0.009

f_3=0.009

From the question we are told that

d(v)= \frac{2.15v^2}{64.4f}

Generally the equation for the f is mathematically given as

f= \frac{2.15v^2}{64.4*d(v)}

Therefore

For v=20 and f=38

f= \frac{2.15(20)^2}{64.4*(38)(20)}

f=0.02

For v=30 and f=86

f=\frac{2.15(30)^2}{64.4*(86)(30)}

f=0.01

For v=40 and f=153

f=\frac{2.15(40)^2}{64.4*(153)(40)}

f=0.009

Volume decreases more when sides are divided than volume divided.

Volume is an amount of a substance that can be stored in a closed place.

Given that,

The volume of a cube is given by V(x) = x³

To verify claim,

Let the side of cube is 4⇒x=4,

Then volume of the cube  V= (4)³ ⇒V = 64

According to the condition,

Half of the volume = 64/2 = 32

When side is divided in half, then side x=2

And volume V= (2)³ = 8

This implies that, the volume is more when volume is divided in half than sides are divided in half.

Therefore, friend's statement is wrong.

Answer:

2 gallons of pure alcohol

Step-by-step explanation:

Let x represent the number of gallons of pure alcohol needed, and create an equation:

4(0.25) + x(1) = (x + 4)0.5

1 + x = 0.5x + 2

x = 0.5x + 1

0.5x = 1

x = 2

So, 2 gallons of pure alcohol should be added.

Answer: Equation that represents this situation is 5(x+17) = 1495,

Price of one ticket is 282

Step-by-step explanation:

Here x represents the price of one ticket,

Also, a person bought travel insurance that costs $17 per ticket.

Hence, the total cost of a person = x + 17

⇒ The total cost of 5 person = 5 ( x + 17 )

But, According to the question,

5 ( x + 17 ) = 1495

⇒ x + 17 = 299

⇒ x = 299 - 17

⇒ x = 282
