Answer:
you multiply the circumference by the radius squared
Ex.) (c= circumference)
c=3.14x2r
3 - 2a > 7
We need to solve for a
First, let's subtract 3 on both sides to have the variables on a side and the numbers on another side:
3 - 2a > 7
3 - 2a - 3 > 7 - 3
- 2a > 4
Let's divide both sides by -2 to have a on side and its value on the other side:
-2a > 4
(-2a)/(-2) > (4/-2)
a < -2 (In a case of an inequality, we change the sign when we divide by a negative number to its opposite).
So 3 - 2a > 7 when a < -2 (answer c)
Hope this helps! :D

Just do 0.25 (25%) times 395
its the same as doing 395 divided by 25
multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
There would be 3 triangles formed.
Each interior angle of a triangle will sum up to 180 degrees.
The 1st triangle will have 130,25, and 25 as its angle measures.
The angle 130 degrees will be divided into 2 to create 2 right triangle. Each triangle will have angle measurements of 25, 65, and 90 degrees.
