We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c 
21 = 1 x 2 + c 
c = 19 
therefore, the equation is y = x + 19
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
Let the length be x
then width  = x-2
44 ft = 2(l+b)
44ft = 2(x + x-2)
44ft  =  2(2x-2)
44 ft = 4x -4
44+4 = 4x
48 = 4x
x = 48/4 = 12
Length = <u>x = 12</u>
Width = <u>x-2 = 12-2 =10</u>
<u></u>
<u>Length is 12 and width is 10</u>
<u></u>
<u>check if its correct </u>
2(l+b) = 44
2(12+10)=44
2(22) = 44
 
        
             
        
        
        
Answer: 160
Step-by-step explanation:
So here they are telling you that there are 4 twelves, a.k.a 4 groups of 12. Which means that you have to multiply 4 x 12 = 48
Then there are 7 sixteens, a.k.a 7 groups of 16.
Which also means that you have to multiply 7 x 16 = 112
Add both numbers and there you have your answer!
I hope you found my answer helpful! :)
