Step-by-step explanation:
(2*5)*4 = 10*4 = 40
2*(5*4) = 2*20 = 40
Answer: An opposite definition would be "A shape with a set of points that DOES NOT have the same distance from a given point."
Step-by-step explanation: No need for step-by-step explanations.
None of these. All of these functions are defined as ratio of trigonometric functions.
Trigonometric functions have infinite zeroes, so when you put them in the denominator, they lead to infinitely many points of ill-definition.
Specifically, we have:

which is undefined at

Take the sqrt of both sides of <span>(x+2)^2=10:
x+2 = plus or minus sqrt(10)
Solve for x: x = -2 plus or minus sqrt(10)
Evaluate x: x = -2 + sqrt(10) AND x = -2 - sqrt(10) (answers)

Answer:
Perimeter of a triangle = 2*(length + breadth)
SO = 2*18+41
= 77 is the perimeter
