Area of the Rectangle = bh = 8(17)=136

Area of a Triangle = \frac{bh}{2}=\frac{8(17)}{2}=\frac{136}{2}=68

Take both areas and subtract them:

136-68=68

This means shaded area = 68 in^2

Hope this helps!

It's 68". Because a triangle in a rectangle that spans all sides is half the area of the rectangle.

Some of the steps in the derivation of the quadratic formula are shown.
Leokris [45]

Answer:

(C)The square root of terms separated by addition and subtraction cannot be calculated individually.

Step-by-step explanation:

In Step 7:

\dfrac{\pm\sqrt{b^2-4ac} }{2a} =x+\dfrac{b }{2a}

The expression \pm\sqrt{b^2-4ac} cannot be written as b \pm\sqrt{4ac}. This is as a result of the fact that square roots of terms separated by addition and subtraction cannot be calculated individually.

Take these examples:

\sqrt{9-4} =\sqrt{5} \\\sqrt{9}-\sqrt{4}=3-2=1\\ $Clearly \sqrt{5}\neq 1\\$Similarly\\\sqrt{9+4} =\sqrt{13} \\\sqrt{9}+\sqrt{4}=3+2=5\\ $Clearly \sqrt{13}\neq 5\\
