<span> (6y^2 + 4y + 5) – (3 – 7y + y^2)
= </span><span> 6y^2 + 4y + 5 – 3 + 7y - y^2
= 5</span>y^2 + 11y + 2

Answer:
I will use two different type of prisms:
Triangular prism:
The volume is equal to the area of the triangle multiplied by the heigt of the prism.
So:
300m^3 = A*H
Suppose that the triangle is a triangle rectangle with two equal cathetus of lenght L = 6m, then the area of the triangle is:
A = 6m*6m/2 = 18m^2
300m^3 = 18m^2*H
H = 300/18 m = 16.6m
So this prism is a triangular prism where the area of the triangular face is 18m^2 and the height is 16.6m
Rectangular prism:
Here the volume of the prism is:
V = W*H*L
Where W is the width, H is the heigth and L is the length.
300m = W*H*L
now we can assign values to two of the values and then find the other value.
Suppose W = 30m, H = 5m
300m^3 = 30m*5m*L = 150m^2*L
L = 300/150 m = 2m
So this prism has a width of 30m, a height of 5m and a length of 2m.
Answer:
Yes, ALL equilateral triangles are similar. By definition they all have the characteristics given above, which means that they are all completely proportional, which means they are all similar.
(4,3). When you reflect across the y axis, the X changes from negative (4) to positive (4)
