Answer:
C. 16 cm
Step-by-step explanation:
Top side: 2 + 4 = 6
Right side: 1 + 1 = 2
Bottom: 2 + 4 = 6
Left side: 1 + 1 = 2
6+6+2+2 = 16 cm.
The perimeter of any figure, is all its sides summed up
now, notice the picture below, using the 30-60-90 rule, that's "x"
now, get the other sides, since you know what "x" is, and sum them up, that's the perimeter
So to solve for y, subtract 108 from each side.
The equation becomes -y=126
Since you don't want y to be negative then divide each side by -1 this will flip all of the signs (positives become negative and vice versa) without changing the number.
So the equation is now y= -126
Answer: 0.57 = 57/100 this means it has to be rational.
Explanation: You have to explain to them that any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.
