Answer:
the square root of 3200
Step-by-step explanation:
I'm not sure if this is right, because the format of the question wasn't clear, but it sounded like we have to find the diagonal distance of the room from one corner to the opposite. If the sides are 40ft long on both sides, we can use the Pythagorean Theorem to solve this:
40^2+40^2=c^2
1600+1600=c^2
3200=c^2
c=sqrt(3200)
or about 56.5
Let's check with the pythagoras theorem,
65² = 33² + 56²
4225 = 1089 + 3136
4225 = 4225
As it obeys it, It is a right angle triangle.
Hope this helps!
a perfect square trinomial, (x + y)² = x² + 2xy + y²
so, if we have the x of the bx, what is left is the b
the expression would have to be (x + 7)², since we have the 49 and the x²
so, what's left: x² + 14x + 49,
b = 14
