Hello :
<span>h(x) = 6x² − 60x + 147= (x² -2(30)x+30²)-30²+147
</span>h(x) = (x-30)²-753 .....(vertex form)
<span>the axis of symmetry is the line of equation : x=30</span>
Answer:
4860 ft^2
Step-by-step explanation:
9 feet is represented by 1 inch.
● 9 => 1
Square both sides
● 81 => 1
So a 81 ft^2 square is represented by a 1 in^2 square (picture below)

The gym's area in the blueprint is 60 in^2
That 60 1in^2 squares.
● 1 => 81
● 1×60 => 81×60
We have multiplied both sides by 60
● 60 => 4860
So the original are is 4860 ft^2
One Triangle = 6 + 6 + 5 = 17.
Two Triangles = 6 + 6 + 5 + 5 = 22.
Three Triangles = 6 + 6 + 5 + 5 + 5 = 27.
4-10 and 4+(-10)
4-(-10) and 4+10
-4-(-10) and -4+(-10)
And the last two should be the last pair
