Answer:
Perimeter: 36 cm
Step-by-step explanation:
Area = length x width
Width = x
Length 2x
Area = 72 cm
Area = x (2x) = 2x^2
2x^2 = 72 cm
x^2 = 72/2
x = sqrt 36 = 6
Width = 6
Length = 12
Perimeter = 2(6) + 2(12) = 12 + 24 = 36 cm
The first answer is [7, (infinity symbol) )
the second one is (1, (infinity symbol) )
Answer:
x = 3
Step-by-step explanation:
12 * (3) = 36. 36 / 12 = (3)
The answer is D, as it asks for the sum of x and y, not the difference.
