Answer:
20(x+15)(x+10)
Step-by-step explanation:
Hi there!
As your question states, we need to fully factor the polynomial: 20x²+500x+3000
These are pretty big numbers; let's pull out the GCF, as that will make it easier to factor
the GCF is 20
so factoring 20 out of the polynomial will get:
20(x²+25x+150)
As you can see, the polynomial inside the parenthesis is a lot easier to factor than the original with really big numbers.
Now use FOIL to factor x²+25x+150 into 2 binomials
25 is the sum of the last terms
150 is the product of the last terms
think: which two numbers add up to 25 but multiply to get 150?
those two numbers are 15 and 10
x²+25x+150 factored is (x+15)(x+10)
but remember we have the 20 in front of x²+25x+150 (or now, (x+15)(x+10))
therefore the fully factored binomial is 20(x+15)(x+10)
Hope this helps! :)
Answer: f & b
Step-by-step explanation:
for example both leave the digits unchanged and an identity is an element of a set which, if combined with another element by a specified binary operation, leaves that element unchanged.
6 is the answer I believe
Which of the following relations has a domain of {−5, 0, 5}? {(−5, 0), (0, 5), (1, 0)} {(−5, 5), (0, 5), (5, 5)} {(0, −5), (0, 0

Answer:
It's so easy. Domain is the set made up of the first elements of each ordered pair (x, y).
Look at the second relation {(-5, 5), (0, 5), (5, 5)}. It has three ordered pairs which arw (-5, 5), (0, 5) and (5, 5).
First element of the first ordered pair (-5, 5) is -5. First element of the second ordered pair (0, 5) is 0. First element of the third ordered pair (5, 5) is 5.
So, the set made up of the first elements of the ordered pairs is {-5, 0, 5} and hence it is the domain.
