(x + 3)^3 = (x + 3)(x + 3)(x + 3) = (x + 3)(x^2 + 6x + 9) = x^3 + 9x^2 + 27x + 27
Answer:
D. 1800°
Step-by-step explanation:
The given polygon has 12 sides.
The formula for finding the sum of the interior angles of an n-sided polygon is given as, ( n − 2 ) × 180.
Where n is the number of sides of the polygon.
Thus, the sum of the interior angles of the 12 sided polygon given above is:
(12 - 2) × 180
= 10 × 180 = 1800°
<em>Sum of the measures of the interior angles of the 12-sided polygon is D. 1800°</em>
<h2>
The value of x = - </h2>
Step-by-step explanation:
The given expressiona are:
and
To find, the value of x = ?
∴
By crossmultiplication, we get
4(3x + 2) = 2(3x - 6)
⇒ 12x + 8 = 6x - 12
⇒ 12x - 6x = - 12 - 8
⇒ 6x = - 20
⇒ 3x = - 10
⇒ x = -
∴ The value of x = -
Thus, the value of x is equal to - .
