Answer:

d. x = 4 and x = –10

Step-by-step explanation:

(x+3)^2=49

Take the square root of each side

sqrt((x+3)^2)=±sqrt(49)

x+3 = ±7

Separate into 2 equations

x+3 = 7           x+3 = -7

Subtract 3 from each side

x+3-3=7-3         x+3-3 = -7-3

x =4                   x =-10

Which perfect square equation represents x^2+4x+1=0 by completing the square?
natali 33 [55]
First thing to do is to move the constant over to the other side of the equals sign.  Then we will complete the square on the x terms.  We will take half the linear term, square it, then add it to both sides.  Our linear term is 4.  Half of 4 is 2, and 2 squared is 4. x^2+4x+4=-1+4.  In the process of completing the square we have created a perfect square binomial on the left which is (x+2)^2=3.  A is our answer.

Imagine that you are planning to estimate the price of the average book at your college bookstore. The bookstore carries 13,000
mafiozo [28]

Answer: "13,000 books" represents the population.

"200" books represents the sample.

Step-by-step explanation:

  • A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
  • A subset of population is known as ample.
  • When population is too large to the researcher  , then it uses sample to represent the entire population.

Here,  "13,000 books" represents the population.

"200" books represents the sample which is a subset of 13,000 books.
