Answer:
Step-by-step explanation:
First, turn the word problem into an equation:
n(a number) was divided by 2

followed by this quotient beying multiplied by 4
 *4
*4
the product was added to 9
 *4+9
*4+9
the total sum was 25
 *4+9 = 25
*4+9 = 25
use PEMDAS to solve the equation
subtract 9 on both sides
 *4 = 16
*4 = 16
cancel the 2 and the 4 using factorization
n*2 = 16
divide 2 on both sides
n = 8

Answer:
There are 24 squares
Step-by-step explanation:
By taking the small triangles and connecting them to make squares and adding those to the number of squares already there there are 24 squares in total.
 
        
             
        
        
        
The first table is a quadratic function while the second table is a linear function.
<h3>How to Interpret Function Tables?</h3>
1) For the first table, we have;
x y
0 5
1 0
2 -3
3 -4
4 -3
x = 2  and x = 4 have same value of y = -3  and as such it will be a Quadratic Function.
y = x²  - 6x + 5
2) For the second table, we have;
x y
2 5
5 14
6 17
8 23
10 29
This table is a Linear function because  slope is same and equal to 3 all through. Thus, the equation is y = 3x - 1  
3) For the third table, we have;
x y
-3 8
-2 4
-1 2
0 1
1 0.5
This is an exponential function because equation can be modelled by;
y = 2⁻ˣ

f(x) = -3x - 5, g(x) = 4x - 2
(f - g)(x) = f(x) - g(x) = (-3x - 5) - (4x - 2) = -3x - 5 - 4x + 2 = (-3x - 4x) + (-5 + 2)
(f - g)(x) = -7x - 3
