The formula for the volume of pyramid is,

Here, B is base area and height of pyramid.
The volume expression for group 4 is,

Here, expression,

represents the base area and 9 represent the height of pyramid.
So height of the pyramid created by group 4 is 9.
Answer: 9
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up
Hope this helps :)

Answer:
There are no true solutions to the equation.
Step-by-step explanation:
<u><em>The correct equation is</em></u>

Solve for y
squared both sides






<em>Verify</em>
substitute the value of y in the original expression

----> is not true
therefore
There are no true solutions to the equation.
