Given that points B, D, F are the midpoints of sides of triangle ΔACE.

Using Triangle's Mid-segment theorem, we can say that a line joining midpoints of two sides of a triangle is parallel and half of the length of the third side.

It means DF║AC and DF = \frac{AC}{2}

Given DF = 15 in the question, so AC = 2·DF = 2×15 = 30.

So, AC = 30 is the final answer.

Answer:

4.0.

Step-by-step explanation:

In sample 1, you do 0.65/1.3 which gets you to 0.5, so then you do the same to the bottom which you also have to divide by 1.3, and 5.2/1.3 is 4.0 or 4.

Answer:

408 in²

Step-by-step explanation:

A rectangular prism has 6 rectangular faces.

Opposite faces are congruent

2 faces at (6 × 9) = 2 × 54 = 108 in²

2 faces at (9 × 10) = 2 × 90 = 180 in²

2 faces at (6 × 10) = 2 × 60 = 120 in²

surface area = 108 + 180 + 120 = 408 in²
