If Y is between X and Z, then X, Y, and Z are collinear?

1 answer:

8 0

I think, I'd go with A) Always true. As 2 points is always the line. If you add third one, it will be collinear.

Put the values in place of the corresponding variables and do the arithmetic.

$\sqrt{(a)(b)}=\sqrt{(14)(3)}=\boxed{\sqrt{42}\approx6.48074}$

The area A of a trapezoid with height h and bases b₁ and b₂ is equal to the average of the bases times the height:

A = (b₁ + b₂) h / 2

We're given A = 864, h = 24, and one of the bases has length 30, so

864 = (b₁ + 30) 24 / 2

864 = (b₁ + 30) 12

72 = b₁ + 30

b₁ = 42
