Actual:
15 ft wide and 10 ft high.
Area = 15ft * 10ft
Area = 150ft²
Scale drawing.
Every 16 inches represent 5 feet in the back drop.
15ft ÷ 5ft = 3 * 16 inches = 48 inches
10ft ÷ 5ft = 2 * 16 inches = 32 inches
Area = 48 in * 32 in
Area = 1536 in²
Area of the scale drawing is 1,536 square inch.
Answer:
D
Step-by-step explanation:
To solve the quadratic equation, use the inverse operation to squaring. This will undo the exponent and allows x to be isolated. The inverse operation is the square root. This is called the square root property of equality.
(x + 2)² = 1
√(x+2)² = √1
(x+2) = ±1
x = 1 -2 and x = -1 - 2
x = -1 and x = -3
The product of the roots -1 and -3 is -1*-3 = 3
