Question 2: Find the area and the circumference of C to the
nearest tenth

9514 1404 393

Step-by-step explanation:

The diameter is the difference between x-coordinates of the end points of the horizontal line through the center:

  d = 12 -2 = 10

The radius is half that, so is ...

  r = d/2 = 10/2 = 5

The area is given by ...

  A = πr^2 = π(5^2) = 25π ≈ 78.5 . . . . square units

The circumference is given by ...

  C = πd = 10π ≈ 31.4 . . . . units

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
