Answer: (x + 3)(x - 4)
Step-by-Step Solution:
We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.
= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)
Answer:
39.6 cm²
Step-by-step explanation:
The formula for the area of a trapezoid is given as:
Area of a Trapezoid = 1/2(a + b) h
Where, from the question:
a = 8.9 cm
b = 5.5 cm
h = 5.5cm
Hence,
1/2 (8.9cm + 5.5cm) × 5.5cm
= 1/2 × 14.4 cm × 5.5 cm
= 39.6 cm²
Area of the Trapezoid = 39.6 cm²
Answer:
3
+ 4
Step-by-step explanation:
If u = < x₁, y₁ > and v = <x₂ , y₂ > , then
u • v = x₁x₂ + y₁y₂
Given
u = < , - 1 > and v = < 3, - 4 >, then
u • v = 3 + (- 1)(- 4) = 3 + 4
Answer:
8 inches cubed
Step-by-step explanation:
Since it is a cube, the length of one side is 2.
To get a volume you have to multiply 2 * 2 * 2.
Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
