Answer: ya
Step-by-step explanation:
Answer
Perimeter of rectangle, P = 2L + 2W
P = 36ft
Width, W
Length, L = W + 2ft
Perimeter of rectangle, P = 2L + 2W
Given; P = 36ft
36ft = 2W + 2(W + 2ft)
36ft = 2W + 2W + 4ft
32ft = 4W
8ft = W
L = W + 2ft
L = 8ft + 2ft
L = 10ft

Answer: x = 4
y = - 3
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x-3y = 13 ------------------------1
2x+4y=-4--------------------------2
We would apply the method of substitution in solving the equations. From equation 1, we would make x to stand alone by adding 3y to the left hand side and the right hand side of the equation. It becomes
x - 3y + 3y = 13 + 3y
x = 13 + 3y
Substituting x = 13 + 3y into equation 2, it becomes
2(13 + 3y) + 4y = - 4
26 + 6y + 4y = - 4
26 + 10y = - 4
Subtracting 26 from the left hand side and the right hand side of the equation, it becomes
26 - 26 + 10y = - 4 - 26
10y = - 30
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10y/10 = - 30/10
y = - 3
Substituting y = - 3 into x = 13 + 3y, it becomes
x = 13 + 3 × - 3
x = 13 - 9
x = 4
