First, we distribute the 2 through the parenthesis.
3x+2x+8=5(x+1)+3
Then we distribute the 5 through the parenthesis 
3x+2x+8=5x+5+3
Collect the like terms
5x+8=5x+5+3
Add the numbers
5x+8=5x+8
The statement is true for any value of x, because both sides are identical
        
             
        
        
        
Answer:
5 row, 3 left
Step-by-step explanation:
She has 48 flowers, 5 flowers one row
How many rows can she make? So divide 
48/ 5
= 9.6
So she can only make 9 rows
The leftovers flowers are the flowers that didn't manage to make 5 per row
Therefore, if she can make 9 rows, in other words 9 x 5 = 45
45 flowers were able to be placed in a sequence of 5 per row
So the ones that are left is 
48 - 45
= 3
 
        
             
        
        
        
Answer:
   x ∈ [-2, 7]
Step-by-step explanation:
The given equation ...
   x^2 -5x -4 ≤ 10
can be rewritten as ...
   x^2 -5x -14 ≤ 0
and factored as ...
   (x +2)(x -7) ≤ 0
Clearly, the "or equal to" condition will be met when x=-2 and x=7. For values of x between these numbers, one factor is negative and the other is positive. Hence the product will be negative. So, numbers in that interval are the solution set.
   x ∈ [-2, 7]
 
        
             
        
        
        
Answer:
1863 
Step-by-step explanation:
( 23 x 12 ) x 2 = 552
69 x 19 = 1311
  1311
<u>+552</u>
= 1863
