A number plus twice the number is equal to three times the number?
A + 2a = 3a
What is you called when the prime factorization of a number is 1 and itself?
You is called a prime number!You is called a prime number!You is called a prime number!You is called a prime number!
What is a prime number times a prime number?
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
Is 101 a prime or composite number?
101 is a prime number. The only factor of 101 is itself and 1.prime
Is 19 a prim number or a composite number?
19 is a prime number.19 is a prime number.19 is a prime number.19 is a prime number.
Does the difference of two squares number always factorable?
No. If the two numbers are consecutive then the difference of their squares need not be factorisable. For example, 4^3 - 3^3 = 16 - 9 = 7, which is a prime. If the smaller number is a then this simply requires that 2a+1 is a prime.
What is the number of terms in 2a + 3b is?
5
What is 2 to the power of 0 why?
20 = 1Consider what is the value of 2a ÷ 2a? Any number divided by itself is 1. Thus:2a ÷ 2a = 1The law of indices says that when dividing, they are subtracted, for example:25 ÷ 22 = (2 x 2 x 2 x 2 x 2) ÷ (2 x 2) = 2 x 2 x 2 = 23 = 25-2So 2a ÷ 2a is (also):2a ÷ 2a = 2a-a = 20Since any number subtracted from itself is 0 (= a - a). This must have the same value as before, thus:20 = 1The 2 above can be replaced by any number x which means that any number to the power 0 is 1:x0 = 1
A number plus twice the number is equal to three times the number?
A + 2a = 3a
What four consecutive even numbers have a sum of 412?
As all the required numbers are even, we can identify the smallest value number as 2a, then the other three consecutive even numbers are (2a + 2), (2a + 4) and (2a + 6). The sum of these four numbers is, 2a + (2a + 2) + (2a + 4) + (2a + 6) = 8a + 12 Then, 8a + 12 = 412 8a = 412 - 12 = 400 2a = 400 / 4 = 100 The four consecutive even numbers are 100, 102, 104 & 106. NOTE : In this problem the choice of 'a' as the smallest value number would have achieved the correct answer but in other situations such a choice could have resulted in 4 consecutive ODD numbers being found. When in doubt use 2a or similar to clearly identify that the number is even.
What is 2a plus 3?
9a +8 -2a -3 -5a = 2a +5
If a number doubles it is raised to what power?
The answer really depends on what number you are doubling. Let's say that you wish to double the number a (which we assume is greater than 0). If we're raising a to the nth power, then n must satisfy the following equation: an = 2a Taking the natural log on both sides, n log a = log (2a), n = log (2a) / log a. So if we double the number a, it is raised to the log (2a) / log a power.
What is the group number for Radium in the periodic table?

Are a negative number and a positive like terms?
i think yes, because you can combine 2 and -2, which are like terms, so why not 2a and -2a?
How do you solve 19a 2a-4a 3a?
You don't have a number alone. Also I'll make the assumption that it is 19a+2a-4a+3a Without a number alone, it can't really be solved, unless a=0 19a+2a-4a+3a can be simplified however to 20a
Why 7 is not a prime number?
