Ok, so for this problem you want to get Y all by itself.
First you’ll want to move your X variables to one side. You do that by adding 2X to both sides of the equation. This will cancel out the -2X and it will turn the 16X into an 18X.
You’re equation is now,
18X+9=9Y
Next you’ll want to divide both sides by 9 so that you’ll get Y all by itself.
Your equation should look like this.
Y=2X+1!
And that’s your answer:) I hope this helped!
The total surface area of the given pyramid is:
A = 39ft²
<h3>
How to get the surface area of the given figure?</h3>
The total surface area will be equal to the sum of the areas of the square and the 4 triangles.
Remember that for a square of side length S, the area is:
A = S².
In this case, S = 3ft, then:
A = (3ft)² = 9ft².
Now, the area of a triangle of base B and height H is:
A = B*H/2.
Here we can see that the triangles have a base of 3ft (the sides of the square) and a height of 5ft, then the area of each triangle is:
A = (3ft)*(5ft)/2 = 7.5 ft²
Then the total area of the figure is:
A = 4*(7.5 ft²) + 9ft² = 39ft²
