I’d say 21 tbh unless the sum is half of the brothers age then it would be 9
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:

When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes

Rewrite as:

Divide both sides by 16t

Hence, it takes the rocket 25 seconds to hit the ground

Answer:
1. x + 24 = 3x
24 = 3x - x
24 = 2x
12 = x
3x
3 (12)
36
2. 10x - 27 = 7x
10x - 7x = 27
3x = 27
x = 9
7x
7 (9)
63
3. 5x + 1 = 6x - 13
5x - 6x = -13 - 1
-x = -14
x = 14
5x + 1
5 (14) + 1
71
4. 6x + 3 = 4x + 39
6x - 4x = 39 - 3
2x = 36
x = 18
6x + 3
6 (18) + 3
111
1. B
2. A

Answer:
Step-by-step explanation:
If Jemini divides 5x4−6x+1 by x+2, he will need to use the long division method for him to proceed to the correct answer. The answer gotten is known as the quotient. Find the solution in the attachment.
