Hi there! I can help you! 8 + (-9) + (-2). When adding negative integers, you have to subtract. 8 - 9 is -1 and -1 - 2 is -3. You would have to start at 8 and go to the left 11 times to land on -3. The sum to the problem is -3.
36 / 9 equals 4 so the problem is basically 10 + 4 which is 14.
Answer:
Step-by-step explanation:
2(13x – 7). 11.
The correct answer is x^2-2x+2=0
The explanation is shown below:
1. To solve the problem shown in the figure above, you must apply the following proccedure:
2. You have that the roots of the quadratic equation shown in the figure attached in the problem are:
x=-1±i
3. Then, you know the quadratic formula to solve quadratic equations, which is:
(-b±√(b^2-4ac))/2a
4. You can see in the figure that a=1 and c=2; then, by analizing this, you can conclude that the coefficient b is:
b=-2
5. Therefore, you can conclude tha the quadratic equation is:
x^2-2x+2=0
6. If you want to verify it, apply the quadratic formula to the quadratic equation shown above and you will obtain the roots shown in the figure.
Answer:
52
Step-by-step explanation:
When asked such a question, try to use trial and error.
For example, the total is 202 and is made of of 4 integers which are <u>consecutive</u>(follow each other)
If you were to divide 202 by 4, you would get approximately 50
So, it would be best to try and add certain consecutive numbers(making sure 50 is one of them) till you get a total of 202
In this case, the integers would be, <em>49, 50, 51</em> and <em>52</em>
The question then further asks you ti find out which is the greatest of these integers. That would be <em>52</em>
