What is the answer to 8(s^2+2s+3)+(2s+s+1)

Mathematics
1 answer:
Inessa05 [86]3 years ago
4 0

Answer:

s = (i sqrt(439))/16 - 19/16 or s = -(i sqrt(439))/16 - 19/16

Step-by-step explanation:

Solve for s:

1 + 3 s + 8 (s^2 + 2 s + 3) = 0

Expand out terms of the left hand side:

8 s^2 + 19 s + 25 = 0

Divide both sides by 8:

s^2 + (19 s)/8 + 25/8 = 0

Subtract 25/8 from both sides:

s^2 + (19 s)/8 = -25/8

Add 361/256 to both sides:

s^2 + (19 s)/8 + 361/256 = -439/256

Write the left hand side as a square:

(s + 19/16)^2 = -439/256

Take the square root of both sides:

s + 19/16 = (i sqrt(439))/16 or s + 19/16 = -(i sqrt(439))/16

Subtract 19/16 from both sides:

s = (i sqrt(439))/16 - 19/16 or s + 19/16 = -(i sqrt(439))/16

Subtract 19/16 from both sides:

Answer:  s = (i sqrt(439))/16 - 19/16 or s = -(i sqrt(439))/16 - 19/16

An established company started with 147 employees. After 10 years in business, they now have 283 employees. What is the percent
xeze [42]
So, Increase = New Number - Original Number. Therefore, Increase = 283 - 147 which equals 136.
136 = 283 - 147.
Then you want to divide the increase by the original number and multiply the answer by 100.
136/147 = 0.92
0.92 * 100 = 92.

Final Answer: The employee count has increased by 92%. I hope this helps.

A grocery store recieves a 180-pound crate containing six 10-pound bags of potatos and an unknown number of 5-pound bags of pota
Diano4ka-milaya [45]

Answer:

60+5x = 180    

Step-by-step explanation:

Let the number of bags of potatoes be x.

We have been given that a grocery store receives a 180-pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes.

The weight of 6 potato bags of 10 pound each will be 6\times 10=60 pounds.

We can write an equation for the number of bags of potatoes by equating the weight of six 10-pound bags of potatoes and x 5-pound bags of potatoes with 180 pounds.  

6*10+5x = 180

60+5x = 180

Therefore, the equation that represents the number of bags of potatoes in the crate is 60+5x = 180.

Determine the values of "m" and "n" so the number would be in scientific notation:
Andreyy89

Answer:

79,000= 79•10^3

Step-by-step explanation:

so the amount of 0's = the power of 10.

In this situation there is 3 0's . so the power of ten will be 10^3

and then the number before the 0's will equal m

so m = 79 n = 3

And also (just as a side note) you can use the asterisk mark (*) as the multiplication symbol. on most keyboards the command is ctrl + 8. you can also use a bullet point (•) for multiplication symbol the command for that is alt + 0149
