BigorU [14]
Area of entire trapezoid = <span>((sum of the bases) ÷ 2) • height
Trapezoid Area = (51 / 2) * 26
</span><span>Trapezoid Area = 663

UN-shaded triangle area = .5 * base * height
</span><span>UN-shaded triangle area = .5 * 23 * 26
</span><span>UN-shaded triangle area = 299

SHADED Trapezoid Area = 663 -299

What is the solution of the following system <br> x-y=11<br> -x+y=-11
Elan Coil [88]
The answer is infinitely many solutions.
 
<span>x - y = 11
-x + y = -11
_____
Express the first equation in the term of x and substitute it into the second equation:
x = y + 11
</span>-x + y = -11
_______
-(y + 11) + y = -11
-y - 11 + y = -11
-y + y = 11 - 11

Which will have a greater effect on the volume of the prism: doubling the height or doubling the width? Explain your reasons.
statuscvo [17]
Doubling the width has a greater effect on volume.
The volume of a prism is calculated by this formula:
<span>Prism Volume = Area of Base • Height
The </span><span>Area of the Base </span>is calculated by this formula:
area = n * side² / (4*tan(180 / # of sides)

So, we see that doubling the width (the side length) will increase the volume by 4 whereas doubling the height only doubles the volume.
