Answer: D
Step-by-step explanation:
To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.
[subtract both sides by 1/2x]
[add both sides by 1]
[multiply both sides by 4]

Now that we know x, we can plug it into each expression to find teh length of each side.
[multiply]
[subtract]

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.
23+23+23+23=92 or 23×4=92
Since we know that the perimeter is 92 units, the answer is D.
Answer:
- Collect like terms and simplify
- Subtract 7 from both sides

$539 - $35 = $504
$504 : 12 = $42
Per month you pay $42.
Firstly , we can draw diagram
we can see that
adjacent = 850
opposite =250
so, we can use tan formula
