We are given : 5a^2-25a
Please note: We always check Greatest Common Factor (GCF) first when factoring a polynomial.
If Greatest Common Factor (GCF) exist we factor out GCF.
In the given polynomial, we can see that greatest common factor of 5a^2 and 25a is 5a.
So, we would factor out GCF 5a first.
In order to factor out GCF, we need to divide all terms of the polynomila by GCF we got.
If we factor out 5a from 5a^2 -25a, we need to divide 5a^2 and -25a by 5a.
On dividing 5a^2 by 5a we get a and
on dividing -25a by 5a we get -5.
Therefore, on factoring out 5a, we get
5a(a-5).
Therefore, we use Greatest Common Factor (GCF) method of factoring.
Because if you reduce by find their common factors you can see that 2,3 is the same at 4,6. 2,3 times 2 gives you 4,6. Hence forth they are the same line
Answer:
a= v+w-k
Step-by-step explanation:
Get 'a' by itself to make it a solvable equation
so, subtract k from both sides so it can cancel itself on the 'a' side
Changing the coefficient of x to 6 changes the meaning of the expression as 5 is added to 6 times x
Solution:
Given that number 2 in the expression 5 + 2x is called the coefficient of x
We are asked to find what happens when changing the coefficient to 6 changes the meaning of the expression
In the expression,
5 + 2x
This means 5 is added to 2 times x or 5 is added to twice of x
Number 2 is called the coefficient of x
When we change this coefficient to 6, the expression becomes,
5 + 6x
So now the meaning of expression becomes,
5 is added to 6 times x
So changing the coefficient of x changes the meaning of the expression
Answer: $12,000
Step-by-step explanation:
Miguel makes 6% on every sale he makes and wants to make $600 in commissions.
The amount he needs to sell is therefore the amount that has $600 as 5% of it.
Assume the amount of insurance needed is x.
x * 5% = 600
x = 600 / 5%
x = $12,000
