as we know perimeter of a square is 4 x side
one side is 3n + 2
4 sides = 4(3n +2)
The answer is 30%) because all the angles of a triangle needs to add up to 180 so 180-75-75= 30
She can buy 5more guppies because she spent $50 in total because 32+12+6= 50 dollars.So she has $30 dollars left $6 per guppy × 5 guppies = $30 so she can buy 5 more
Answer:

Step-by-step explanation:
we know that
An <u><em>equilateral triangle</em></u> has three equal sides and three equal interior angles (each interior angle measure 60 degrees)
so
The perimeter is equal to

where
b is the length side of the equilateral triangle
we have

substitute

solve for b

Find the area
The formula of area applying the law of sines is equal to

substitute the value of b
