Answer:
The total surface area of a regular hexagonal pyramid is 146.2 cm².
Step-by-step explanation:
The base is a regular hexagon 4cm on a side. its height is 8 cm.
The total surface area of a pyramid with regular hexagon base
Where, a represents the base edge and h represents the height of the pyramid.
The area of given regular hexagonal pyramid is
The total surface area of a regular hexagonal pyramid is 146.2 cm².
Use the slope formula and slope-intercept form Y=Mx+b to find the equation.

<h3>The equation is:</h3><h3>
</h3><h3>The number is 3 or 4</h3><h3><em><u>Solution:</u></em></h3>
Given that,
7 added to the square of a number is equal to 7 times the number, minus 5
Let "x" be the unknown number
From given,
7 added to square of x = 7 times the x minus, 5
Solve the above equation
Split the middle term
We have two solutions
x - 3 = 0
x = 3
And
x - 4 = 0
x = 4
Thus number is 3 or 4
Answer: The answer is 896.
Step-by-step explanation: There are several ways to answer this. If you multiply both the 28 and the 32 you get the final answer 896 quickly.
However there are different ways to get the answer that aren't as quick as this one.
First we multiply.
<em>30*20=600 </em>
Then we continue multiplying.
<em>8*30=240 </em>
<em>20*2=40 </em>
<em>8*2=16 </em>
Then we add all the values up starting with the hundreds
<em>600+240=840. </em>
<em>40+16=56</em>
Finally we add both of the values up and we get our answer <em>840+56=896. </em>
<u><em>A=896 Hope this helps!</em></u>
