A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Subtract the smallest number from the largest number.


Is 27 divisiable by all numbers?

NO, it is not divisible by all numbers. This is easy to see if you remember that 27 is an odd number and odd numbers are NOT divisible by 2. Then there is the issue that is is NOT divisible by any number greater than itself. That is a lots of numbers that don't work!


What number is divisible by 5 and 9 not 10 and its a 4 digit number and it contains on 2 different numbers?

The number is divisible by 5 then its end is either 0 or 5 The number is divisible by 9 then the sum of its digits is divisible by 9 If the number is divisible by 5 but not by 10 then it means that the number is divisible by 5 but not by 2, thus it's not an even number. The number is not even so it ends with 5 So the number is written a5a5 or aa55 or 5aa5. a+5+a+5 = 2 x a+10 which must be divisible by 9 if a = 1 then is doesn't work if a = 2 then is doesn't work if a = 3 then is doesn't work if a = 4 then 4545 or 4455 or 5445 are ok if a = 5 then is doesn't work if a = 6 then is doesn't work if a = 7 then is doesn't work if a = 8 then is doesn't work if a = 9 then is doesn't work


What number is divisible by 2 3 6 9?

The number 2,3,6 and 9 are all divisible by 324...Multiply 2,3,6 and 9; then you get 324 as you answer. To check your work divide all the numbers by 324.


How do even and odd numbers work?

Not sure what you mean with "work"; an even number is a number that is divisible by 2, that is, if you divide it by 2, you get no remainder. An odd number, if divided by 2, has a remainder of 1.


Why is that when a number is divisible by 2 and divisible by3 it is also by six how are they related why does this pattern not work for 2 4and 8?

Numbers divisible by 6 will have at least one 2 and one 3 as prime factors because 2 x 3 = 6. The same is true for 2, 4 and 8. Numbers divisible by 4 are also divisible by 2. Numbers divisible by 8 are also divisible by 4 and 2.


How would you reconise a multiple of three?

if the number is a 2 or more diget number, you add up all of the numbers in the number and when you have the sum, if the sum is divisible by 3 , the whole number is divisible by three EX. 123=6, 6 is divisible by 3 so 123 is divisible by three 447=15 is divisible by 3 so 447 is divisible by 3 989=26 is *NOT* divisible by 3 so 989 is not divisible by three this truly does work for every single number


How many four digit numbers which are divisible by 7?

Best way to work this out: find the highest number below 10,000 that is divisible by 7 (9,996) and divide that by 7 (1,428). 1,428 is the amount of one-, two-, three- and four-digit numbers divisible by 7. Now find the number of one-, two- and three-digit numbers divisible by 7 (which is 994/7 = 142) and subtract this number from 1,428, giving us 1,286.


What is a four digit number divisible by 3 and 5 but not 4?

If it's to be divisible by 5, it must end in 5 or 0. And if it's to be divisible by 3, adding the digits together must result in a multiple of 3.While some numbers that end in zero will still work, you can guarantee that the number won't be divisible by four by choosing a number that ends in five.So you'd need a four-digit number, that ends in 5, whose digits add up to a multiple of 3. The smallest such number would be 1005, and the largest would be 9975.(However, the actual largest number that would fit your question is 9990; remember that I did say some numbers that end in zero would still work.)


To find a composite number why divide by prime numbers?

You could try dividing by composite numbers but the number that you are testing is divisible by a composite number, then it will be divisible by a prime factor of that composite number and that prime factor will be smaller. It is always easier to work with smaller numbers.


In mathematics how do you work out the range?

The Range is the distance on the number line that the smallest number is from the biggest number, in sbsolute value. Basically, to find it using math, you would subtract the smallest number in the series of numbers from the largest number in the same series.


What are 3 consecutive numbers whose sum is 125?

That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
