Well if you set the equation equal to zero X will equal negative 4 so if you take your other answer choices and equal them to zero whichever one x equals negative 4 that's your answer
Answer: 
Step-by-step explanation:
For this exercise you need to find the Least Common Multiple (LCM).
The steps two find the Least Common Multiple are shown below:
1. Descompose the numbers into their prime factors.
2. Multiply the commons an non commons with the highest exponent. The product obtained will be the Least Common Multiple.
Knowing this, you can find the Least Common Multiple between 7 and 11. This is:

Therefore the smallest number of biscuits each must have baked is: 
Answer:
c) 1 & 3 only
Step-by-step explanation:
In the picture attached, an example of an inscribed angle is shown.
In the example, the vertex is point B, which lies on the circle.
A chord of a circle is a straight line segment whose endpoints both lie on the circle, like segments BA and BC from the picture
Answer:
sqrt(24)
Step-by-step explanation:
The number is slightly less than 5
We know that 5^2 =25
sqrt(25) = 5
so the number has to be less that sqrt(25)
The only number less than sqrt(25) is sqrt(24) and sqrt(20)
sqrt(20) is too far away to be slightly less than 5 so it must be sqrt(24)
