Answer:
![62.4$ cm^2](https://tex.z-dn.net/?f=62.4%24%20cm%5E2)
Step-by-step explanation:
The net of the triangular pyramid is attached below.
Since each of the faces is an equilateral triangle of side 6cm, the base of the pyramid will also be an equilateral triangle of side lengths 6cm .
In the equilateral triangles
Therefore, the surface area of the pyramid formed from the net shown
= 4 X Area of One Triangular Face
![=4 (\frac12 \times bh)\\=4 (\frac12 \times 6\times 5.2)\\=4(15.6)\\=62.4$ cm^2](https://tex.z-dn.net/?f=%3D4%20%28%5Cfrac12%20%5Ctimes%20bh%29%5C%5C%3D4%20%28%5Cfrac12%20%5Ctimes%206%5Ctimes%205.2%29%5C%5C%3D4%2815.6%29%5C%5C%3D62.4%24%20cm%5E2)

2.2
Step-by-step explanation:
so you do it like this:
Since the fraction is 5/11 you take the demoniator which is 11 and you divide it by 5.
Answer:
y=2x+7
Step-by-step explanation:
When an equation is parallel to another, it shares the same slope.
Our original line is y=2x-8, and it is in slope-intercept form (y=mx+b)
This means that our slope is 2 because m represents the slope.
The slope of our parallel line will then also be 2.
<u>We can begin to plug that into point-slope form which is:</u>
y - y1 = m(x - x1)
This is where (x1, y1) is a point the line intersects, and m is the slope.
<u>Plugging in the slope, we'll have:</u>
y - y1 = 2(x - x1)
We also know it intersects the point (-4, -1)
We can plug this into our equation as well.
y - (-1) = m(x - (-4))
y+1=2(x+4)
<u>Now, we can simplify it into slope-intercept form:</u>
y+1=2(x+4)
Distribute
y+1=2x+8
Subtract 1 from both sides
y=2x+8-1
y=2x+7
