Here, we may use Geometric Progression
The sequence follows as:
27, 18,12,...
The first term (a)= 27
27/18 = 18/12
common ratio = 1.5
Let fourth term be x
Therefore , 12/x = 1.5
=> x= 12/1.5 = 8
Answer:
(2x + 11)(2x - 11)
Step-by-step explanation:
4x² - 121
rewrite the expression in the form of (a)² - (b)²:
(2x)² - (11)²
difference of squares a²-b²=(a+b)(a-b):
(2x + 11)(2x - 11)
Answer:
∠ 2 = 60°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles fro 180° for ∠ 2, that is
∠ 2 = 180° - (57 + 63)° = 180° - 120° = 60°
