+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=−4
ab=4
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 4.
−1,−4
−2,−2
Calculate the sum for each pair.
−1−4=−5
−2−2=−4
The solution is the pair that gives sum −4.
a=−2
b=−2
Rewrite factored expression (x+a)(x+b) using the obtained values.

When the survey results came back employees indicated that the lighting in the building is too low. There are 50 lights in the building it will cost 50 to replace each light the new lights are led lights that are brighter and more efficient and last 10 years it will save the company 305 per year in energy cost plus make a brighter more productive work space making employees happier how many years will it take for the new lights to pay for themselves round to the nearest year
Answers
Answer:
8 years
Step-by-step explanation:
There are 50 lights present in the building and each light cost $50. Therefore the cost of changing all the bulbs is:
Cost = number of lights * cost per light = 50 lights * $50 = $2500
Changing the lights in the building save the company $305 per year in energy cost. Therefore, the number of years required for the new lights to pay for themselves is:
number of years = cost of changing bulbs / money saved per year
number of years = $2500 / $305 per year = 8.2
number of years = 8 years to the nearest year

Help would be appreciated! (Will give brainliest) Please don’t give me invalid answers on purpose :(
Thanks!
Answers
Answer:
Yes, (0, 1) is the solution of the given inequality.
Step-by-step explanation:
To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.
If the inequality is true for the ordered pair it will be the solution.
Inequality is,
y > x - 1
For (0, 1),
1 > 0 - 1
1 > -1
True.
Therefore, ordered pair (0, 1) is the solution of the given inequality.

Submit Answer
Answers
Answer:
6/5
Step-by-step explanation:
you'd divide the second number by the first number
30/25= 6/5
The fraction in the simplest terms, is 6/5 which is multiplied by the first number by to get the second.
What is fraction?A fraction is a part of a whole number, and a way to split up a number into equal parts. It is written as the number of equal parts being counted, called the numerator, over the number of parts in the whole, called the denominator.
Given that, what fraction should be multiplied to 25 to get 30,
Let the fraction be x/y
Therefore,
25·x/y = 30
x/y = 30/25
x/y = 6/5
Hence, the fraction in the simplest terms, is 6/5 which is multiplied by the first number by to get the second.
