» Which three cards have equal values? 3 x 42

4 x 32

3 (40 + 2)

4x (30 + 20)

(3 x 40) + (3 x 2)

(4 x 3) + (4 x 2)

 3 x 42 , 3(40 +2), (3 x 40) + (3 x 2)

Step-by-step explanation:

3 x 42 = 126

4 x 32 = 128

3 ( 40 + 2) = 3 x 40 + 3 x 2 = 126

4x ( 30 + 20) = 4x x 30 + 4x x 20 = 200x

(3 x 40) + (3 x 2) = 126

( 4 x 3) + ( 4 x 2) = 20

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

you'll have to attache the image of the bar graph in order for us to answer : )
