When will the GCF of a pair of numbers be equal to 1?
When none of the numbers in the pair are prime
When one of the numbers in the pair is prime
When both numbers in the pair are prime
When both pairs do not have any common factors
Select all the correct methods to find the LCM of a pair of numbers.
Get the prime factorization of the pair of numbers and look for the smallest factor
Work the prime factorization of the pair at the same time and multiply all the prime numbers
We can list out the prime factors of both numbers and multiply all the factors together
We can list out the multiples of both numbers until we see one of the multiples match the other

If m=3 and b=6, what is the correct linear equation?
The U-shaped graph created by a quadratic equation is:
The vertex
A line
A parabola
The minimum
What are the values of a, b, and c in the quadratic equation 3x2 + 4x - 10 = 0 ?
a = 3x2 b = -10 c = -4x
a = 3 b = -10 c = -4
a = 3 b = -4 c = -10
a = 3 b = 4 c = -10
x = 2 and -2
Simplify the expression:
5a + 2b - 3a + 4
8a + 2b + 4
2a + 2b + 4
8ab
4ab + 4
Evaluate 2a + 4b
if a = 10 and b = 6

What is a right triangle?
A triangle where all sides equal 90 degrees
A triangle where every angle is 90 degrees
A triangle where all three sides are equal
A triangle where there is a 90 degree angle
The Pythagorean Theorem says:
a + b = c
a2 + b2 = c2
a2 + b2 + c2
c = ab/2
