Answer:
The original side length of the square was 9 ft
Step-by-step explanation:
Consider that the square was initially of side length "x" (our unknown). Then the sides were all increased by 5 ft, and now the perimeter (addition of all four sides) of the square render 56 ft.
Let's write an equation that represents the addition of the four sides of this new rectangle, and set it equal to 56 ft. Then solve for the unknown "x":
Therefore, the original side of the square was 9 ft.
Standard form of linear eqn : y=mx+c
m= gradient
c= y intercept
Line that is parallel = Same Gradient
Eqn of 2nd Line : y=0.75x+c
Given (8,0) where x=8 and y =0,
0=(0.75)(8) + c
c = -6
Therefore y=0.75x-6
Answer:
x = 30 + 56

There would be 7 in 4 rows
Answer:
1. y = 2m + 4
2. y = 3m + 1
3. y = 2/3m +1
4. y = 4m -6
Will answer any questions in the comments
Step-by-step explanation:
1. 1 -> 5 = 4
6 -> 14 = 8
8/4 = 2
y = 2m + 4
2. 2 -> -3 = -5
-5 -> 10 = 15
5/15 = 3
y = 3m + 1
3. 9 -> -3 = -12
11 -> 3 = -8
-8/-12 = 2/3
y = 2/3m + 1
4. 3 -> -2 = -5
6 -> -14 = -20
-20/-5 = 4
y = 4m - 6
