the three prime numbers that equal 17 are _+_+_=17

you need to learn your multiplication tables 2x1=2 2x2=4 2x3=6 2x4=8 2x5=10 2z6=12 2x7=14 2x8=16 2x9=18 2x10=20 so you can tell now how many times 2 goes into 20

The prime factorization of 210 is 2 x 3 x 5 x 7. Every other factor can be made from those numbers. Remember to include 1. 1,2,3,5,7 (2x3, 2x5, 2x7) 6,10,14 Divide 210 by those numbers and you will have the other half of each factor pair. 15,21,30,35,42,70,105,210

To multiply two fractions, the numerator (top part) of the result is the product of the numerators, and the denominator (bottom part) of the result is the product of the denominators. There is no need to convert to a common denominator first; this is only necessary to add, subtract, or compare fractions. For example, 1/2 x 5/7 = (1x5) / (2x7) = 5/14. Note that it is easier to do any simplifications BEFORE doing the actual multiplication.

A good way to remember prime numbers from 1 to 100: Take any number. If it is only divisible by 1 and itself, then it is a prime number. If it is divisible by any other numbers, then it is not a prime number. Example: 13. You can only get 13 by multiplying: 1 x 13, and 13 can only be divided by 13...13/13 = 1...or 1....13/1=13. So 13 IS a Prime number. Example 14. You can get 14 by multiplying: 1x14, 2x7, and you can divide 14 by 2 to get 7, or by 7 to get 2, so 14 is NOT a Prime number, since numbers other than itself and 1 are able to be divided into it to get whole numbers. This test will hold true for any prime number.

I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.

19 - 2*7 + 98/14 = 12.
