Answer: (no promises this is exactly right)
-2r+6
Step-by-step explanation:
−3r+9+r+−3
=
(−3r+r)+(9+−3)
=

The expression that gives the number of Jackets that can be made from a fabric of 1634 yards will be found as follows:
let the number of jackets be x.
the total length of material required to make x jackets cannot exceed 1634 yards, it can be equal to or less than 1634. Thus, the expression will be given as follows:
amount required to make one jacket is 378,hence:
378x≤1634
x≤4.32275
approximating the above we get:
x≤4
        
                    
             
        
        
        
Answer:
-1
Step-by-step explanation:
slope=(y2-y1)/(x2-x1)
 =4-(-1)/-1-4
 =5/-5

Answer:
+ 2 for the top row and -10 from bottom row
Step-by-step explanation:
-2 + 2 = 0
0 + 2 = 2
2 + 2 = 4
15 - 10 = 5 
5 - 10 = -5
-5 - 10 = -15
 
        
             
        
        
        
Answer:
x = 6
Step-by-step explanation:
The isosceles triangle is divided into two forming two right triangles
in right triangles the square value of hypotenuse is equal to sum of other two side lengths
x^2 + 4^2 = 52
x^2 + 16 = 52 subtract 16 from both sides
x^2 = 36 find the root for both sides
x = 6
