Answer:
A. 2 distinct roots.
Step-by-step explanation:
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
Answer:
Answer: There are 21 eggs left.
Step-by-step explanation:
One carton has 12 eggs.
2 cartons are two times one carton, so two cartons have 2 times 12 eggs.
2 * 12 = 24
There are 24 eggs in two cartons.
Margot uses 3 eggs. We subtract 3 eggs from 24 eggs.
24 - 3 = 21
Answer: There are 21 eggs left.
The LCM of 20 and 300 is 300.
<h3>How to find the LCM?</h3>
