Because when you're working with real wood and tools and glass, there's
no such thing as negative length. 

One of the square roots of every number is negative.  When you're working with
a real window, the area still has two square roots, but you ignore the negative
one, because it has no physical significance in the real world and it can't help
you, so it's no good for anything.

BartSMP [9]

Answer: the slope of green line = -\frac37

Step-by-step explanation:

We know that,

If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.

Given: The red line and the green line are parallel.

The slope of red line = -\frac37

Then, the slope of green line = -\frac37  [Slopes of two parallel lines are equal]

Hence, the slope of green line = -\frac37

Write two polynomials with a difference of 2x2 + x + 3
Anettt [7]

Answer:

The two polynomial CAN be 5x^4+5x^3+8x^2+x+6 and 5x^4+5x^3+8x^2+2x+13.

Step-by-step explanation:

Step 1: <u>Simplify the expression:</u>

2*2 + x + 3

4+x+3

x+7

Step 2: <u>Think of a random polynomial:</u>

5x^4+5x^3+8x^2+x+6

Step 3: <u>Either add your "random polynomial" by </u>x+7<u> or subtract it.</u>

<u>I want to add it so...</u>

5x^4+5x^3+8x^2+x+6+x+7

= 5x^4+5x^3+8x^2+2x+13

 Check by subtracting  5x^4+5x^3+8x^2+x+6 and 5x^4+5x^3+8x^2+2x+13.

         5x^4+5x^3+8x^2+2x+13

   -      5x^4+5x^3+8x^2+x+6

        _____________________

         0x^4 - 0x^3 -0x^2 +x +7 <em><u>or  </u></em>x+7<em><u /></em>
