Answer:
B. 3(a + 7) + 3/(a + 2)
Step-by-step explanation:
Just substitute (a+2) in for every (x) in the equation:
f(a + 2) = 3 ((a + 2) + 5) + 4/(a+2)
= 3 (a + 7) + 4/(a+2)
The law of cosines is
c= square root of a^2 + b^2 - 2ab cos c
the law of sines is
a = b(sin a /sin b)

Discussion
6 gift boxes are 12.36 inches high
32 gift box are x inches high
This is a proportion question. A proportion is made of 2 equal ratios. If you know 3 parts of the proportion, you can solve for the 4th,
6/32 = 12.36/x Cross multiply
6x = 12.36 * 32 Combine the right.
6x = 395.52 Divide by 6
6x/6 = 395.52/6
x = 65.92
Answer: 65.92
Note
Using a proportion saves you the trouble of finding 1 box and multiplying whatever number you get by 32

Answer:
the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
Step-by-step explanation:
Let the number of adult tickets sold be x and number of student tickets sold be y !
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em> Total 267 tickets were sold
i.e, x + y = 267
x = 267 - y .... ( i )
Also, The number of student tickets sold was two times the number of adult tickets sold.
i.e, y = 2x ...... ( ii )
putting value of x from ( i ) in ( ii )
y = 2 ( 267 - y )
y = 534 - 2y
3y = 534
y = 534/3
y = 178
also, x = 267 - y
x = 267 - 178
x = 89
So, the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
