Answer:
The length is 12metres, the width is 6metres
Step-by-step explanation:
Suppose the width is x, the length is x+6
The square is 72. The square of rectangular field is equal to product of length and width.
so x(x+6)=72
x^2+6x-72=0
a=1 b=6 c=-72
D= b^2-4ac= 6*6+288= 36+288= 324
sqrtD= 18
x1= (-b-sqrtD)/2a=(-6-18)/2= -12 (it is negative, but width is only positive. So this root doesn't match)
x2=(-b+sqrtD)/2a= (-6+18)/2= 12/2=6 - the width
The length is 6+6=12

Answer:
y = 15x
Step-by-step explanation:
You can identify the slope (constant of proportionality) by finding y when x = 1. That value is 15. It goes into the equation as the coefficient of x.
y = 15x
Since they are vertical angles, they are equal.
5x - 53 = 3x - 7
2x = 46
x = 23

Answer:
I know a bit about Angle Bisectors. (the line that splits an angle into 2 equal angles)
Answer:
equation of a line= y-y¹=m(x-x¹)
y--1.8=7(x-0)
y+1.8=7x-0
y+1.8=7x
y=7x+1.8
