Sry I'm couldn't solve the second one but the ans for the 1st is 504 sq units
        
             
        
        
        
Answer:
x=(y+9)/(1+2w)
Step-by-step explanation:
x-9+2wx=y
We make x the subject
x+2wx=y+9
x(1+2w)=y+9
Divide both sides by (1+2w)
x(1+2w)/(1+2w)=y+9(1+2w)
x=(y+9)/(1+2w)

Answer:
D
Step-by-step explanation:
The y-intercept must be at -7, so that eliminates C. 
Because of the direction of the line, the slope needs to be negative. This eliminates B. 
The slope of the line is -7/6, so D is the correct answer. 
 
 
        
             
        
        
        
Answer:
7
Step-by-step explanation:
First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3
Which gives you 2/3 (9x - 6)
Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3 
then you divide 6/3 with 2 
Getting 2 (3x - 2)
The use the distributive law
2 x 3x - 2 x 2
simplify the equation
6x - 4
expand 4 (x +2) + 2:   4x + 10
which then equals 6x-4=4x+10
add 4 to both sides
6x-4+4=4x+10+4
simplify
6x=4x+14
subtract 4x from both sides
simplify again
2x=14
divide both sides by 2
2x/2 = 14/2 
simplify one last time and get the answer
x=7
