Answer:
1. D
2. C
3. C, A F
Step-by-step explanation:
We will find the answer using the second law of motion i.e. Force is equal to the product of mass and acceleration.

Where,
- F is force
- M is mass
- A is acceleration
In our case,
Let's solve for M ~




<em>Thus, The mass of object is 36.36 </em><em>grams</em><em>.</em><em>.</em><em>.</em><em>~</em>
..........................
Distribute.
(a + 8)(a -3)
FOIL:
First, Outside, Inside, and Last
a * a = a^2
a * 3 = 3a
8 * a = 8a
8 * -3 = - 24
a^2 + 11a - 24
Distributed Expression: a^2 + 11a - 24
