Answer: 2 rational solutions
Step-by-step explanation:
When the discriminant, b² + 2a, is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7
Answer:
x < 12
Step-by-step explanation:
Note that the symbol for:
"less than" is <
"greater than" is >
"less than or equal to" is ≤
"greater than or equal to" is ≥
In this case, the question states that the variable "x" is less than 12. Set the equation: x < 12
x < 12 is your answer.

One way to find the least common multiple of two numbers is to first list the prime factors of each number.
8 = 2 x 2 x 2
Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
2: three occurrences
3: one occurrence
So, our LCM should be
2 x 2 x 2 x 3 = 24.
So, Marco can buy, at the very least, 24 beads of each color to have equal colors of beads.
