A. 9x² + 6x + 35
B. 9x² + 36x + 35
C. 9x²- 36x - 35
D. 9x² - 36x + 35

Answers

Answer 1

Answer:

Answer:

$9x^2-36x+35$

Step-by-step explanation:

Simplify the product using FOIL.

(3x - 7 ) (3x - 5)

Apply FOIL method to multiply it

multiply 3x inside the second parenthesis and then multiply -7 inside the second parenthesis.

$(3x)(3x - 5)= 9x^2-15x$

$(-7)(3x - 5)= -21x+35$

Write all the terms together

$9x^2-15x-21x+35$

Combine like terms

$9x^2-36x+35$

Answer 2

Answer: F) 3x*3x= 9x²
O) 3x*-5= -15x
I) -7*3x= -21x
L) -7*-5= 35
equation would be 9x²-36x+35

How do I solve for the equation s=3f-24? Solve for f

Answers

s-3f=-24
-3f=-24-s
3f=24+s
f=24+s/3

Final answer:

To solve for 'f' in the algebraic equation 's=3f-24', add 24 to 's' and then divide the result by 3.

Explanation:

To solve the algebraic equation 's=3f-24' for 'f', you would first decide to isolate 'f'. To do this, start by getting rid of the '-24' on the right side of the equation by adding 24 to both sides. This would simplify the equation to 's+24=3f'. Next, divide both sides of the equation by 3. This step will result in a final solution of 'f=(s+24)/3'. So, to solve for 'f' in the provided equation, simply add 24 to the original 's' value and then divide the result by 3.

63 because if you look at the pattern each number is multiplied by seven so if you multiply the input which is nine by seven you would get 63.

in an ordinary day with no discount if u see the parretn you can get the cost per ticket by dividing the cost by number of tickets
1st : 21/3 =7
2nd: 35/5=7
3rd: 56/8 = 7
so the ticket in an ordinary day = $7
in friday they make discount by $2 so the new value of the ticket = the old value -2
so the ticket on friday = $5
so if you want 9 tickets
9*5 = $45
