I want to know hot solve this problem

I think the answer is A but can be simplified as seen in my photo above

Answer

C

Step-by-step explanation:

( factorise numerator and denominator )

w^2 - 9 ← is a difference of squares and factors as

w² - 9 = (w - 3)(w + 3)

w² - 4w - 21

Consider the factors of the constant term (- 21) which sum to give the coefficient of the w- term ( - 4)

The factors are - 7 and + 3 , since

- 7 × + 3 = - 21 and - 7 + 3 = - 4 , then

w² - 4w - 21 = (w - 7)(w + 3)

Then

← cancel the common factor (w + 3) on numerator/ denominator

= → C

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
