Answer:
The answer is B.
Step-by-step explanation:
They both have the same equation (65x32) but A has -20.
Therefore, A is <u>20 less</u> than B
I hope this helps :)
Option A is the answer
Since 29 + 39 = 68, the answer cannot be possible.
Essentially, any two sides of a triangle have to be greater than another side.
The correct match are as follows:
<span>1. Plane.
</span>B) a flat surface that extends infinitely and has no depth; it has length and width
<span>2. Perpendicular Lines.
</span><span>D) two lines that intersect at 90˚ angles.
</span><span>
3. Parallel Lines.
</span><span>A) two lines that lie within the same plane and never intersect.
</span><span>
4. Circle.
</span><span>C) a set of all points in a plane that are a given distance from a point.

5. Angle
</span><span>E) a figure consisting of two rays with a common endpoint.</span>
Answer:
adds nutrients to the soil
soil gains fertility
suitable for fruits and vegetables gives fresh outcomes by composting
The denominator of the first term is a difference of squares, such that
4<em>a</em> ² - <em>b</em> ² = (2<em>a</em>)² - <em>b</em> ² = (2<em>a</em> - <em>b</em>) (2<em>a</em> + <em>b</em>)
So you can write the fractions as
(4<em>a</em> ² + <em>b</em> ²)/((2<em>a</em> - <em>b</em>) (2<em>a</em> + <em>b</em>)) - (2<em>a</em> - <em>b</em>)/(2<em>a</em> + <em>b</em>)
Multiply through the second fraction by 2<em>a</em> - <em>b</em> to get a common denominator:
(4<em>a</em> ² + <em>b</em> ²)/((2<em>a</em> - <em>b</em>) (2<em>a</em> + <em>b</em>)) - (2<em>a</em> - <em>b</em>)²/((2<em>a</em> + <em>b</em>) (2<em>a</em> - <em>b</em>))
((4<em>a</em> ² + <em>b</em> ²) - (2<em>a</em> - <em>b</em>)²) / ((2<em>a</em> - <em>b</em>) (2<em>a</em> + <em>b</em>))
Expand the numerator:
(4<em>a</em> ² + <em>b</em> ²) - (2<em>a</em> - <em>b</em>)²
(4<em>a</em> ² + <em>b</em> ²) - (4<em>a</em> ² - 4<em>ab</em> + <em>b</em> ²)
4<em>ab</em>
<em />
So the original expression reduces to
4<em>ab</em> / ((2<em>a</em> - <em>b</em>) (2<em>a</em> + <em>b</em>))
or
4<em>ab</em> / (4<em>a</em> ² - <em>b</em> ²)
upon condensing the denominator again.
