Answer:
Let b=x
Such that b^2 =8b-8 will x^2=8x-8
Using the almighty quadratic formula
x1={-b+sqrt (b^2-4ac)}/2a
x2={-b-sqrt (b^2-4ac)}/2a
From the question
a=1
b=8
c=-8
x1={-8+sqrt (8^2-4(-8))}/2
x1=(-8+5.66)/2
x1=-1.17
x2={-8-sqrt (8^2-4(-8))}/2
x2=(-8-5.66)/2
x2=-6.83
:.(x1,x2)=(-1.17,-6.83)
Step-by-step explanation:
<h2><em>
The area of the pyramid net is 12 units</em></h2>
Step 1
Find the area of the Square in the middle
Formula for finding square:
Let's apply the formula and find our answer:
<em>The area of the square is 4 units</em>
<em></em>
Step 2
Find the area of all 4 triangles around the square
As you know, the formula for finding 1 triangle is as follows:
But, to find the area of 2 triangles, we can use this formula:
And to find 4 of them (with same dimensions;as required here), we can use this one:
Let's apply the formula then! What are we waiting for!!!!
<em></em>
<em>The area of ALL of the triangles around the square is 8 units</em>
<em></em>
Step 3
Add all areas to find FINAL ANSWER!
Easy!
4+8=12
