7 has no factors except ' 1 ' and itself, so it's a "prime" number.
If it were not a prime number, it would be a "composite" one instead.
In expanded form, the answer would look like this:
100,000 + 10,000 + 4,000 + 6
Answer:
Step-by-step explanation:
8.18
Explanation:
The given <em>expression</em> is not an <em>equation</em>. There is nothing that can be <em>solved</em>.
___
An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.
For example, we might have ...
5n +1 = 1
Your familiarity with math facts means you know that ...
0 +1 = 1
In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is <em>n = 0</em>, because 5×0 + 1 = 1 is a true statement.
___
An <em>expression</em> can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.
To evaluate 5n+1 for n=6 we put 6 in place of n:
5×6 +1
Doing the arithmetic, we get ...
= 30 +1 = 31
The value of 5n+1 for n=6 is 31.
Answer:
-111
Step-by-step explanation:
substitute 5 in place of each x
-4(5)^2 - 3(5) + 4
then evaluate or type it into your calculator
-100 - 15 + 4
