Step-by-step explanation:
by definition, the square root of an negative number is known as an imaginary number. i.e Not a real number
= = i (imaginary number)
Answer:
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Step-by-step explanation:
x = length, making the width (x-4)
The stage closet will be (x-4)(8)(1/2)
The rectangle is 7(3)
That makes the painted area x(x-4) - 4(x-4)
So...
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Lowest Common Factor of 5, 3 = 15
This is a square with area 36 in^2
So dimensions are 6 * 6 ins and perimeter = 24 ins.
