Solve x^2+20x+100=50

uysha [10]

1. You con solve the quadratic equation x^2+20x+100=50 by following the proccedure below:

2. Pass the number 50 from the right member to the left member. Then you obtain:

x^2+20x+100-50=0
 x^2+20x+50=0

3. Then, you must apply the quadratic equation, which is:

x=(-b±√(b^2-4ac))/2a

x^2+20x+50=0

a=1
b=20
c=50

4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:

-10±5√2 (It is the last option).

I need help I failing

Liono4ka [1.6K]

Answer:

A and C

Step-by-step explanation:

Both A and C are the same shape, same size, but C is flipped over. If you were to cut out the two shapes and put them over one another, they would be the same. You can also count the blocks that are in the shape itself to see if they match.

The longer side on both has 2.5 blocks in it, the side is two blocks tall, and the smaller line has 1.5 of the block shown.

I'll will implement a sketch to show you what I mean and submit it here. Look at it if you are still confused

I hope this helps!

Determine which situation is represented by the given dot plot. A. Each of Jessica's 6 friends has between $0 and $15 in his or

Rzqust [24]

B. Henry has 15 classmates and each has between 0 and 6 pets.

Step-by-step explanation:

We have been given a dot-plot and we are asked to select the correct situation represented by given dot-plot.

A. Each of Jessica's 6 friends has between $0 and $15 in his or her wallet.

We can see that total number of dots is 15 (2+4+2+3+2+1+1) and no point represents 15 dots. The situation would have been true for each of Jessica's 15 friends has between $0 and $6 in his or her wallet. Therefore, option A is not a correct choice.

B. Henry has 15 classmates and each has between 0 and 6 pets.

Since the total number of dots is 15, so we can say that each dot represents Henry's friend. Since our range is 0 to 6, so the numbers on line represents number of pets. Therefore, option B is the correct choice.

C. Billy bought 0 and 6 shirts from each of his favorite 6 stores.

We can see the largest number of dots on a point is 4, so the largest number of shirts bought by Billy should be 4. Since 6 dots are not on any point, therefore, this is not a correct choice.

D. Across the state, 15 cities were given a score between 0 and 15 regarding the cleanliness of their community.

Since there are 15 dots, so we can say that each dot plot represents one city. But the range of line is from 0 to 6, therefore, it can represent a score between 0 and 6, therefore, option d is not a correct choice.
