Answer:

Step-by-step explanation:
This is a multiplication problem.
We want to multiply 
We factor to get:

We now cancel out the common factors to get:

We now multiply the numerators and the denominators separately to get.
This simplifies to 
Therefore the simplified expression is 
Answer:
72
Step-by-step explanation:
l = 5w
A = l*w
180 = 5w *w
180 = 5w^2
Divide each side by 5
180/5 = 5w^2 /5
36 = w^2
Taking the square root of each side
sqrt(36) = sqrt(w)^2
6 =w
l = 5w = 5*6 = 30
The perimeter is
P = 2(l+w)
P = 2(6+30) = 2(36) = 72
A is 400
E I don't know soory
Answer:
B
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (1, - 2)
d =
