X^2 and 5x both have x in common to factor out. To add or subtract them, 5x^2 is the least common denominator .
Answer:
30 feet is represented by 3 3/4 inches on the drawing
Step-by-step explanation:
We have the relation as;
1 inch = 8 feet
Thus;
3 3/4 inches = x feet
x = 3 3/4 * 8
x = 15/4 * 8
x = 30 feet

Answer:
10,080 minutes
Step-by-step explanation:
First find how many minutes are in a day. There are 60 in an hour and there are 24 hours in a day so multiply 60 by 24 to get 1,440. So there are 1440 minutes in a day. Multiply 1440 by 7 to get 10,080.
Answer:
The width and length of rectangle is 12.728 m
Step-by-step explanation:
Let the length of the rectangle = L
let the width of the rectangle = W
The subjective function is given by;
F(p) = 2(L + W)
F = 2L + 2W
Area of the rectangle is given by;
A = LW
LW = 162 ft²
L = 162 / W
Substitute in the value of L into subjective function;

Take the second derivative of the function, to check if it will given a minimum perimeter

Determine the critical points of the first derivative;
df/dw = 0

L = 162 / 12.728
L = 12.728 m
Therefore, the width and length of rectangle is 12.728 m
