Solve by completing the square. q2 + 6q − 13 = 0.

q =  1.69, -7.69 to the nearest hundredth.

Step-by-step explanation:

q^2 + 6q - 13 = 0

(q^2 + 6g  + 9) - 13 - 9 = 0

(q +  3)^2 - 22 = 0

(q + 3)^2 =  22

q + 3 =  +/- √22

q =  √22 - 3, -√22 - 3.

q =  1.69, -7.69.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: -1
