The GCF means Greatest Common Factor. This is the highest possible factor that multiple numbers have in common.
For example, 5 and 10.
5 = 1 x 5
10 = 1 x 10, 2 x 5
They both have 5 as the highest common factor, so 5 is the GCF.
Now that I've broken down what GCF means, let's factor out our numbers.
52= 1 x 52, 2 x 26, 4 x 13.
78= 1 x 78, 2 x 39, 3 x 26, 6 x 13.
These numbers both have 13 as the highest number.
The GCF of 52 and 78 is 13.
I hope this helps!
To check if the pair is on the graph, plug the x value into the x in the equation, and solve. If the solution to the equation matches the y value from your ordered pair, it’s on the graph, so mark “yes”. If the solution isn’t the same, it’s not on the graph, so mark “no”.
Answer:
x=−2,−8
Step-by-step explanation:
Move terms to the left side. Then set each factor equal to zero.
x=−2,−8
Answer:
32 nd term
Step-by-step explanation:
The formula for the sequence is
n² + 1 ( that is 1 added to each square number )
Equate to 1025 and solve for n
n² + 1 = 1025 ( subtract 1 from each side )
n² = 1024 ( take the square root of both sides )
n = 
= 32
