Find the prime factors or state the number is prime 899?

User Avatar
29*31 = 899 therefore it is not a prime number because it has more than two factors.

What is range mean in math?

User Avatar
Here's what you do you find the smallest number and the larger number then subtract. For EXAMPLE: 12,18,22,24,25,32 32-12=20 so your RANGE is 20. The possible x values of a function.

What are the shared prime factors of 36 and 144?

User Avatar
2 and 3. In fact, 2 and 3 are the ONLY prime factors of both. 36 = 22 x 32. 144 = 24 x 32.

What two numbers add to be 6 and multiply to be negative 495?

User Avatar
Mathematically, you are looking to answer the following system of equations: x + y = 6 x * y = -495 This is rather simple. First, determine x in terms of y: x = 6 - y Next, substitute for x in the second equation: (6 - y) * y = -495 Now, solve for y: 6y - y2 = - 495 0 = y2 - 6y - 495 The solution to the above quadratic equation is: y = (6 + sqrt(2016)) / 2 and y = (6 - sqrt(2016)) / 2 reducing that further gives y = 3+6*sqrt(14) or 3-6*sqrt(14) Substituting back in to x=6-y, that means: x = 3-6*sqrt(14) when y = 3+6*sqrt(14) x = 3+6*sqrt(14) when y = 3-6*sqr(14) Thus, the two numbers that satisfy your question are: 3+6*sqrt(14) or approximately 25.449944 and 3-6*sqrt(14) or approximately -19.449944

How do you factor the trinomial 6x2 - 13x - 63?

User Avatar
6x2 - 13x - 63 = (2x - 9)(3x + 7). 6x2 - 13x - 63 since (6)(-63) = -(2*3*9*7) = (-27)(14),then -27 + 14 = -13, I write: = (6x - 27)(6x + 14)/3*2 = (2x - 9)(3x + 7)

How do you factorise 2a plus 4b plus 8c?

User Avatar
2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])

How is a unit rate calculated?

User Avatar
for example, if the question is 24 pineapples per 3 waffles, you divide 24 by 3 and you get 8 pineapples per waffle(the mathematical-ish way to write that is 24 pineapples/waffle.).

What is the least common multiple of 18 and 35?

User Avatar
Factor out each term: 18 = 3 x 6 = 3 x 3 x 2 = 2 x 3² 35 = 5 x 7 Since these terms don't have a common factor, we can multiply all these primes altogether to obtain: 2 x 3² x 5 x 7 = 18 x 35 = 630

What are the Greatest common factor of 63 and 147?

User Avatar
One method is to express each number in terms of its prime factors. 63 = 3 x 3 x 7 = 32 x 7. 147 = 3 x 7 x 7 = 3 x 72. The factors that both numbers have in common are 3 and 7. The Greatest Common Factor (GCF) is 3 x 7 = 21.
