Use the distributive property to expand the expression. −(3x2 + 4y) + (8z2 − 2) a) −3x2 + 4y + 8z2 − 2 b) −3x2 − 4y − 8z2 + 2 c) −3x2 − 4y + 8z2 − 2 d) −3x2 − 4y − 8z2 − 2

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
