Factor the equation:
set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3x-8 = 0
x = 8
Answer:
120 , 300 degrees ( for angles between 0 and 360 degrees).
In radians this is 2π/3, 5π/3 radians.
Step-by-step explanation:
Arctan ( - sq rt 3) is the angles ( in radians or degrees) for which the tangent is - sq rt 3.
Arctan sq rt 3 = 60 degrees or π/3 radians.
As the tangent is negative in the 2nd and 4th quadrants arctan(-sq rt 3) = 120 , 300 degrees.
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
Plug in the values
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
Answer:
The set of integers is closed under addition, subtraction, and multiplication because when I add, subtract, or multiply any integers, the result is always an integer.
