Surface Area Formula [Cube]:
- <em>a</em> is a side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given variables</em>.
<em>a</em> = 6 cm
<u>Step 2: Find Surface Area</u>
- [Surface Area Formula - Cube] Substitute in <em>a</em>:
- Evaluate:
∴ we have found the surface area of the cube to be 216 cm².

Step-by-step explanation:
<u>Step 1: Define</u>
4x - 12 ≤ 16 + 8x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -12 ≤ 16 + 4x
- Subtract 16 on both sides: -28 ≤ 4x
- Divide 4 on both sides: -7 ≤ x
- Rewrite: x ≥ -7
Here we see that any value <em>x</em> greater than or equal to -7 would work as a solution to the inequality.
∴ our answer is -7.
Answer:
Step-by-step explanation:
Given it's a regular poligon, we calculate its angles as follows :
- (6-2)*180/6 get rid of parenthesis
- 4*180/6 then multiply
- 720/6 now divide it
- 120 is the measure of one angle and since it's a regular poligon each angle has same measure
14-6 over 3--2
8/5
