Helloooo! Marie Here!!

The answer is:

B. (x-6)(x + 2)

Explanation:

  • If any individual factor on the left side of thee equation is the same as  0 , the entire thing will be the same as  x- 6 = 0, x + 6 = 0
  • Set the first factor the same as 0 and solve it x = 6
  • Set the next factor equal to 0 and solve it  x = -2
  • The final thing to do is to add all of the answers you got that will make (x - 6) (x + 2) = 0....... x = 6, - 2
  • And thats how you get B. (x-6)(x + 2)

Lee sells electronics. He earns a 5% commission on each sale he makes.
NISA [10]

Answer:

a) c = (5/100)*d

b) c = 0.05*d

c) The ratio between what Lee recieves and what he sold.

d) d = 2000

Step-by-step explanation:

Since Lee earns 5% in commission for each sale then:

a) c = (5/100)*d

b) c = 0.05*d

c) In this context the constant of proportionality means the ratio of the value Lee sold that he'll earn as a comission.

d) Since he wants to earn $100, then c = 100 and we solve for d

c = 0.05*d

100 = 0.05*d

0.05*d = 100

d = 100/0.05 = $2000

He needs to sell $2000.

Help please !!!!! Super hard
Keith_Richards [23]
The image is really unclear but I will assume that the number of teams given = 66
and the formula is
n = \frac{ {t }^{2} - t }{2}
plug in the number of teams
66 = \frac{ {t}^{2} - t }{2}
multiply both sides by two
132 = {t}^{2} - t
subtract 132 from both sides and factor
t = 12

A bag contains 10 red marbles, 15 yellow marbles and 5 green marbles. What is the probability of drawing a red or green marble f
Volgvan
Probability = 

             (number of ways it can come out the way you want)
divided by
             (total number of ways it can come out).

Total number of ways to draw a marble = 30 (marbles in the bag).

Number of ways it can succeed = 15 (number of red or green ones)

Probability = 15/30 = 1/2 = 50% .
