Answer:
x = 21
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 12 , then
sum = 180° × 10 = 1800°
Each of the 12 interior angles = 1800° ÷ 12 = 150
Then
7x + 3 = 150 ( subtract 3 from both sides )
7x = 147 ( divide both sides by 7 )
x = 21
The volume is decided by using the equation V (volume)=a^3. This means you multiply the length x hight x width. So we would do 5 x 4 x 2 which equals 40.
Answer:
No
Step-by-step explanation:
Let's define our 2 terms first.
2x³y
2xy²
We see here that one term has a x³y and the other has a xy² term. Since they are not the same, the 2 terms are <em>not</em> like terms.
