Answer:
L = 6, w = 2
Step-by-step explanation:
Let w = width of rectangle
Let L = length of rectangle
w = L - 4
Area of rectangle = Lw
L (L - 4) = 12
L^2 - 4L = 12
L^2 - 4L - 12 = 0
(L - 6)(L + 2) = 0
L - 6 = 0
L = 6 (the other option doesn't work because dimensions can't be negative)
w = L - 4
w = 6 - 4
w = 2
Double check
A = Lw
A = 6 x 2
A = 12
It matches so we are right.
Answer:
The option A) is correct
"The lines have proportional slopes" is correct
Therefore the given slopes are proportional to each other
Step-by-step explanation:
Given that Line f has a slope of
, and line g has a slope of 
Also given that f and g are distinct lines
To check the proportionality of two slopes :



Therefore the given slopes are proportional to each other
Therefore option A) is correct
"The lines have proportional slopes" is correct

Answer:
There are 76 students:
g + b = 76
girls is 13 more than twice the boys:
g = 2b + 13
replace g with 2b + 13 in 1st equation
2b+13+b = 76
3b + 13 = 76
3b = 63
b = 21 boys
g = 76-21 = 55 girls
