Start at the origin. This is where the x and y axis meet
x axis = horizontal axis numberline
y axis = vertical axis numberline
From the origin, then move 1.5 units to the left. This is what it means when x is negative. We move that amount to the left.
The y coordinate is -1 so we move down 1 unit
Answer: Choice A
I believe the greatest common factor would be 1 because there are no other multiples that are the same. 1•21=21, and1•40=40
Answer:

Step-by-step explanation:
It is already in its simplest form. When you simplify a square root, you break the number down into prime numbers.
For example,
can be changed into
. Since 2 is in there twice, you'd take it out and make
.
13 is already a prime number, so you cannot simplify it further.
Hi!




Explanation: <u><em>You had to used their prime factorization of 240: 2^4*3*5. And the answer it gave us is 4√15 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie</em></u>
