Answer:
Width= 120 ft
Length= 285 ft
Step-by-step explanation:
W= width and (3w-75)= length since it's 75 less than 3 times the width
w+w+(3w-75)+(3w-75)=810
8w-150=810
8w=960
w=120
So the width is 120 ft
Then substitute the 120 in for w in the length
L= 3(120)-75
L=360-75
L=285
So the length is 285 ft
You can check because 120+120+285+285=810, and because 120×3-75=285!
Answer:
The number "3" alone has the degree of 0.
Step-by-step explanation:
This is because when looking at algebraic expression, we look at the exponent of the highest variable. In this case there isn't one. This is the same
as saying a degree of 0, because a variable to the power of zero(unless it has the value of 0) is 1.

Answer:
Distance = |b - c|
Step-by-step explanation:
Suppose a, b, and c are all negative numbers.
We have to describe the way to find the distance between points (a,b) and (a.c).
Since the x-coordinates of the two points are the same and are a, therefore, the distance between the y-coordinates of the two points will give the distance between the two points.
Mathematically the distance d will be given by d = |b - c|, where |x| is the absolute value function of x. (Answer)
