Answer:
Option A. 
Step-by-step explanation:
we know that
The area of the rectangle is equal to
A=LW
where
L is the length of rectangle
W is the width of rectangle
we have
Plot the vertices
see the attached figure
L=AD=BC
W=AB=DC
the formula to calculate the distance between two points is equal to
<em>Find the distance AD</em>
substitute in the formula
<em>Find the distance AB</em>
substitute in the formula
Find the area
Answer:
f(x) = 
Step-by-step explanation:
All you have to do is multiply (x + 1)(x + 2)(x - 4)
You should get
So, f(x) =
Answer:
Ans: (-5, 5)
-5 < x < 5
Step-by-step explanation:
Standard form: f(x) = x^2 - 25 < 0.
First solve x^2 - 25 = 0 --> x = +- 5
Use the algebraic method to solve f(x) < 0. Between the 2 real roots (-5) and (5), f(x) < 0, as opposite in sign to a = 1.
Answer by open interval: (-5, 5)
Answer:
l = 60 feet
Step-by-step explanation:
use the equation and plug in the width(40 feet) for w and perimeter(200 feet) for p.
200 = 2l + 2(40)
then solve for l
200 = 2l + 80
120 = 2l
l = 60 feet
