Answer:
move the constant to the right hand of the side and change the sign
2x>-0.5-5-5
calculate the difference
2x>-6
divide both sides of the inequality by 2
x>-3
solution X>-3
Add them all up.
A triangle has 3 sides, and you said each side is 3. So:
3+3+3 = 9
Answer:
quatrolatiral, square, rectangle
The circumference of a circle is pi x diameter. Therefore, we can use this in reverse order as well.
I’ll be using 3.14 as pi, but if you need a more exact answer you can always use the pi function on a calculator.
37.68/3.14 = 12
Therefore, the diameter must be 12.
Since the radius is half the diameter, we can divide by 2 to find the radius.
12/2 = 6
Therefore, the radius of our circle is 6.
The area of a circle is equal to pi x radius squared.
Since we know our radius, we can solve.
Using PEMDAS, we know to use exponents first, so 6 squared is equal to 36.
From there, we can multiply.
36 x 3.14 = 113.04
And there we have your answer! 113.04 is the area of the circle.
Hope this helped :)
