Answer:
so we have 4(3x + 10)
then we are going to take the 4 and distribute it into our problem 
so: 4(times)3x and then 4( times)10
to get :
<h2>12x+40</h2>

The table you drew under the question is exactly the right way to start.
-- Make a second column, next to the 6 and 7.  This column will be 
the actual number of each thing.
-- You know that there are 42 marbles, so write '42' in the box 
next to the 6, on the 'Marbles' line.
Now you need to figure out what to write in the 'Stones' line, next to the 7.  
--  Look at the 'Marbles' line.  There's a 6 and then a 42.
Ask yourself: "  Self !  What does the 6 have to be multiplied with to get 42 ?"  
-- Whatever the answer is, drop down to the 'Stones' line, 
and multiply the 7 by the same number.
The product is the total number of stones, and it goes in the box.

(The mystery number is 7.  There are 49 stones.)
        
             
        
        
        
Hi there!
Assuming "Find the product" means multiplying (4x-3) by (3x+8) and factor to it's simplest form the answer would be:
12x²+23x-24
The way you solve this is by using the distributive property of multiplication as shown below:
Start by multiplying -3 from (4x-3) by everything in (3x+8)
3x*(-3) = -9x
8*(-3) = -24
Once you've done that you then multiply everything 4x
4x*8 = 32x
4x*3x = 12x²
(Note: when multiplying two of the same variables like x it means you are multiplying x by itself which is the same as x²)
When you put all of this together it looks like this
12x²+32x-9x-24
from there we combine like terms
32x-9x = 23x
to get
12x²+23x-24
I hope this helps! 
God bless,
