Answer:

8x² + 12x – 8

Step-by-step explanation:

From the question given above, the following were obtained:

Length (L) = 2x + 4

Breadth (B) = 4x – 2

Area (A) =..?

The area of a rectangle is given by:

Area (A) = Length (L) × Breadth (B)

A = L × B

Thus with the above formula, we can obtain the area of the rectangle as follow:

Length (L) = 2x + 4

Breadth (B) = 4x – 2

Area (A) =..?

A = L × B

A = (2x + 4) (4x – 2)

Expand

A = 2x(4x – 2) + 4(4x – 2)

A = 8x² – 4x + 16x – 8

A = 8x² + 12x – 8

Therefore, the area of the rectangle is 8x² + 12x – 8

I got C. 92.08

I'm not 100% sure I did this right, but I took the money gained between years nine and eleven and divided it by 2. I tried a few other ways, but none of my answers were choices.

A plane descends to sea level from 36 comma 400 feet after being airborne for 1 and one half hours. The entire flight time is 3

andrew-mc [135]

Answer:

350 feet per minute

Step-by-step explanation:

The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.

This means it took 104 minutes for the plane to descend 36,400 feet.

Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.

Given the lengths of two sides of a triangle, find the range for the length of the third side (between what two numbers should t

frozen [14]

Answer:

The length of the third side of given triangle lies between 6.5 and 19.9.

Step-by-step explanation:

The law of cosine is as follows

$c^{2} =a^{2}+b^{2}+2abcos\alpha$ ---------------1

⇒ a and b are the given sides of the triangle and c is the third side, and $\alpha$ is the angle between a and b .

In equation 1 , the maximum and minimum values of $cos\alpha$ are 1 and -1.

so the value of c lies in between

⇒ $\sqrt{a^{2}+b^{2}-2ab }$ and $\sqrt{a^{2}+b^{2}+2ab }$ = $|a-b| and |a+b|$

Given a=13.2 and b=6.7 so the the side lies in between |13.2-6.7| and |13.2+6.7|

so the third side lies between 6.5 and 19.9

I need help ASAP middle school work.

Arturiano [62]

Answer:

Step-by-step explanation:

For 11 1/2 gallons, he paid $36.80.

We need to find the cost per gallon.

First, converting 11 1/2 gallons to decimal, it is:

1/2 = 0.5

So, 11 1/2 is 11.5 gallons

So, Cost Per Gallon (last week) = $\frac{36.80}{11.5}=3.2$

There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.

5% = 5/100 = 0.05

0.05 * 3.20 = 0.16

So,

3.20 + 0.16 = $3.36 per gallon

Cost Per Gallon (this week) = $3.36

To buy 9 1/4 gallons it would take:

$3.36*9.25=31.08$

Note: 1/4 = 0.25, so 9 1/4 = 9.25

It would cost $31.08 to buy 9.25 gallons this week

Correct answer is B
