D
Step-by-step explanation:
this answer is correct , i think if you think of it in logically
ANSWER
EXPLANATION
The given expression is
The middle radical contains a perfect square.
Note that:
For area, just multiply the length x width
So therefore, multiply 36 inches x 48 inches and there you have it.
Now for the perimeter, it is a little different
You'd have to add the sides up together to get your answer for the perimeter.
So, 36 in + 36 in + 48 in + 48 in = answer
Isolate the variable on one side of the equation and everything else to the opposite side of the variable.
You can isolate the variable by undoing the operations done to the variable.
For example, if we added 5 to x (x + 5) then we would need to undo that operation. We would need to use the inverse of addition. Which is subtraction.
5x + 6 = 2(2x - 3)
5x + 6 = 4x - 6 <-- Distribute the 2
x + 6 = -6 <-- Subtract 4x from each side
x = -12 <-- Subtract 6 from each side
So, x is equal to -12.
The answer if we go by solving only for "r" Will be -2, in other words r=-2
