Answer:

For Task B: 3x^4 - 2x^3

Step-by-step explanation:

Given that Volume = l*w*h, we can plug in the values on the diagram, so we get the equation (3x-2)(\frac{1}{2}x)(2x^2) = (\frac{3}{2} x^2 - x)(2x^2) = 3x^4-2x^3. Hope this helps!!!

Flauer [41]

Okay, so I'm assuming you want to know the intersection?

-5 = -1/2x - 2

-3 = -1/2x

1/2x = 3

x = 6

<h2>Positive and Negative Numbers on the Number Line</h2>

When we add two negative numbers, the result will be negative.

When we add a negative and a positive number, the result can be positive, negative, or equal to zero.

  • Take the absolute values of both numbers (disregard their signs). If the number that was positive is greater, then the result will be positive.
  • If the number that was negative is greater, then the result will be negative.
  • If the two numbers are equal, then the result will be 0.

When we add two positive numbers, the result will be positive.

<h2>Solving the Question</h2><h3><em>j</em> + <em>k</em></h3>

These are both negative numbers. We know this because they are both to the left of 0. When we add two negative numbers, we will get a result that is less than 0.

  • <em>Less than 0</em>

<em />

<h3><em>k</em> + <em>n</em></h3>

<em>k</em> is a negative number while <em>n</em> is a positive number.

Notice that on the number line, <em>k</em> and <em>n</em> appear to be at a equal distance away from 0. This means that if we were to take their absolute values, they would be equal.

This means that adding <em>k</em> and <em>n</em> would result in an answer of 0.

  • <em>Equal to 0</em>

<em />

<h3><em>m</em> + <em>n</em></h3>

<em>m</em> is a negative number while <em>n</em> is a positive number.

Notice that on the number line, <em>n</em> appears to be further away from 0 than <em>m</em> is. <em>m</em> is very close to 0.

This means that the absolute value of <em>n</em> would be greater than that of <em>m</em>. The result would therefore be positive

  • <em>Greater than 0</em>

<em />

<h3><em>k</em> + <em>m</em></h3>

Both these numbers are negative. Adding them would produce a negative result.

  • <em>Less than 0</em>

A woman drives an SUV that gets 11 mi/gal (mpg). Her husband drives a hybrid that gets 60 mpg. Every week, they travel the same
blondinia [14]
Suppose s and h are the mileage numbers for the SUV and Hybrid, respectively. Then if each vehicle drives 1 mile, the total gas consumption is
.. 1/s +1/h
Then the combined mileage is
.. 2/(1/s +1/h) = 2sh/(s+h)

Option 1: s=12, h=60
.. mpg = 2*12*60/(12+60) = 20

Option 2: s=11, h=75
.. mpg = 2*11*75/(11 +75) = 1650/86 ≈ 19.2

In summary,
.. Option 1: 20.0 mpg
.. Option 2: 19.2 mpg
