Work Shown:

4x^2 - 8x - 192

4(x^2 - 2x - 48)

4(x - 8)(x + 6)

We see that (x - 8) is one factor

To factor x^2-2x-48 into (x-8)(x+6), we need to find two numbers that

Through trial and error you should find the two values are -8 and 6 since

-----------

Another approach is to use the quadratic formula to solve x^2-2x-48 = 0. You should find that the two roots are x = 8 and x = -6.

Those two roots lead to the equations x-8 = 0 and x+6 = 0.

Then use the zero product property to get (x-8)(x+6) = 0

This shows that x^2-2x-48 factors to (x-8)(x+6)

Answer:

[tex]w=6.6[/tex]

[tex]18.6:24.8::3:4[/tex]

Step-by-step explanation:

[tex]As\ we\ know\ that,\\(w+12):(3w+5)::3:4\\By\ the\ proportion\ method\ of\ multiplying\ the\ means\ and\ the\ extremes,\\we\ get,\\(w+12)*4=3*(3w+5)\\4w+48=9w+15\\48-15=9w-4w\\33=5w\\[/tex]

[tex]w=33/5\\w=6.6[/tex]

[tex]By\ substituting\ the\ value\ of\ w\ in\ the\ proportion. you\ get:\\(6.6+12)/(3*6.6+5)=3/4\\18.6/24.8=3/4\\18.6:24.8::3:4[/tex]

Answer:

Each payment should be £172.5

Step-by-step explanation:

Cost of electricity for next year = £600

Administration charge = 15%

Daryl wants to pay in four equal instalments throughout the year,

How much should each payment be?

First we need to find the total cost of bill by adding 15% of administration charge by finding 15% of 600

[tex]15\% \:of\: 600\\=\frac{15}{100}\times 600\\= 90[/tex]

So, 15% of 600 is 90

Now adding 90 into the electricity cost:

600+90

= 690

Now, the total cost of electricity bill is £690

Daryl wants to pay in four equal instalments.

So, divide 690 by 4

Each payment for instalments is: [tex]\frac{690}{4} = 172.5[/tex]

So, Each payment should be £172.5

Answer: It is a 6 percent decrease

Step-by-step explanation:

125,000-117,500=7,500

(125,000)(0.06)=7,500

Answer:

Jaycee sold 28 candy bars

Step-by-step explanation:

Jayce and Rylee are selling candy bars for a school fundraiser. Rylee sold 84 candy bars and raised $210. If Jayce raised $70, how many candy bars did he sell?

From the above question:

$210 = 84 candy bars

$70 = x candy bars

Cross Multiply

210 × x = 70 × 84

x = 70 × 84/210

x = 28 candy bars

Therefore, Jaycee sold 28 candy bars

Answer:

5600 square feets

Step-by-step explanation:

Let [tex]l, b[/tex] denote length and breadth of the rectangular shaped bedroom.

The total distance around Regina rectangular shaped bedroom is 300 feet.

[tex]2(l+b)=300\\l+b=150[/tex]

The length of the room is 80 feet.

Put [tex]l=80[/tex]

[tex]80+b=150[/tex]

[tex]b=150-80=70[/tex] feets

Area of the rectangular shaped bedroom [tex]=lb=80(70)=5600[/tex] square feets.

Answer:

Step-by-step explanation:

we need to remove the parenthesis first

x(y-w+z)=xy-xw+xz

Step-by-step explanation:

1 mile is 1760 yards

1 min is 3600 seconds

[tex] \frac{6yards}{second} \times \frac{1mile}{1760yards} \times \frac{3600seconds}{1min} = \frac{?}{?} [/tex]

then you treat the units as variables and solve. I hope I did this right heh...

Answer:

40°

I hope it will be useful.

Step-by-step explanation:

Angles on the same side of the transversal are equal.

Answer:

x=40

Step-by-step explanation:

If m and n are parallel (symbol ||) then the blue angles must be equal.

In other words, 120 must be 3x.

Hence the solution for x is 120 divided by 3, which is 40.

Answer:

D

Step-by-step explanation:

We are given that the side of a square is: 8√12.

And we want to find the area.

The area of a square is given by:

[tex]A=s^2[/tex]

Where s is the side length. Remember that all side lengths in a square are equivalent.

Therefore, by substitution, we acquire:

[tex]A=(8\sqrt{12})^2[/tex]

Evaluate. We can expand:

[tex]A=(8)^2(\sqrt{12})^2[/tex]

Simplify:

[tex]A=64(12)=768\text{ in}^2[/tex]

Hence, our final answer is D.

Answer:

h= −5/6y (negative 5 y over 6)

Step-by-step explanation:

5y+(2)(5)h=4h

Step 1: Add -4h to both sides.

10h+5y+−4h=4h+−4h

6h+5y=0

Step 2: Add -5y to both sides.

6h+5y+−5y=0+−5y

6h=−5y

Step 3: Divide both sides by 6.

6h/6=−5y/6

h=−5/6y

Answer:

h = - 5y/ 6

Step-by-step explanation:

5y + 2 * 5h = 4h

Using BODMAS

Perform multiplication first

5y + 10h = 4h

Collect like terms

5y = 4h - 10h

5y = - 6h

Divide both sides by - 6

5y / - 6 = - 6h / - 6

h = - 5y/ 6

Answer:

$34.78

Step-by-step explanation:

first,  we need to find the value of 1 HCF, so we divide $48.70 by 14, giving us the result of 3.47857143. (rounding that turns out to be 3.48.

next, we need to multiply the cost of 1 HCF by 10, so 3.48 * 10 = 34.78
