Answer: the solution is the product of two factors
Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c
thus putting them together to get -7+c which is just c-7
Answer:
Both statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient.
Step-by-step explanation:
Solving the equation of statement (1) with the quadratic formula:
In this equation, one of the values of x is bigger than -20 but the other is smaller, this statement doesn't give enough information to answer the question.
Solving the quadratic equation of the statement (2):
Again, one of the values of x is bigger than -20 and the other is smaller than -20. But if the information of this statement is considered along with the other x must be equal to -23, that is the value that appears as an answer in both equations, and with this information is possible to answer the question.
Calculate the number of sides<span>. The interior angles are 120°, so the exterior angles are 180° - 120° = 60°. The exterior angles add up to 360°, so if we divide 360° by 60° we find there are 6 exterior angles.

The initial population was 234.
<em><u>Explanation</u></em>
<u>Formula for the exponential growth</u> is: , where P is the initial amount, A is the final amount, r is the rate of growth and t is the time duration.
There was 337 bacteria after 5 minutes and 699 bacteria after 15 minutes. So, the equations will be......
Now dividing equation (2) by equation (1) , we will get .......
<u>Taking 'natural log'</u> on both sides.........
Now, plugging this into equation (1), we will get......
So, the initial population was 234.
