The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
answer:
5.002 inches
step-by-step explanation:
- find the diameter of the circle
- the diameter is the side length of the square since the sides of it are touching the circle
c = 2πr
- c stands for circumference
- π stands for pi (or 3.14)
- r stands for radius
- plug in the values given to find the diameter
c = 2πr
15.71 = 2(3.14)r
15.71 = 6.28r
r = 2.501 (rounded or estimated)
- now that we have the radius, we can find the diameter by multiplying by 2, since diameter is two times bigger than the radius
diameter = 5.002 (estimated)
- now, that will be the side length because the diameter = the side length
1. the answer is D
2. You are correct it is vietnam
3. the answer is 1947
When simplified:
8x^2-8+3x^2+6x
= 11x^2+6x-8
Therefore, the answer would be 3 terms... C.
