Answer:
-9
Step-by-step explanation:
I'm assuming that the lower case c and the upper case C are the same variables.
6C^2 + 2.5D - D + 2C^2 - 3D = 8C^2 - 1.5D

- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define variables</u>
∅ = 39°
opposite leg = 9
hypotenuse = x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin39° = 9/x
- Multiply <em>x</em> on both sides: xsin39° = 9
- Isolate <em>x</em>: x = 9/sin39°
- Evaluate: x = 14.3011
- Round: x ≈ 14.30
Since there are 6 sides to a cube we can divide the total surface area by 6 to find the area of a single side
384 / 6 = 64
since the side of a cube is a square the sides are the same length, so we need a number, that when multiplied by itself is 64. The answer is 8
