6. Circle all the expressions that are equivalent to this expression: 6p+ 7. You will lose a point for every wrong expression that you circle.

1.p+2+52 +5

2. 42p

3. 7p +6

4. 3p + 2p + P +7

5. 13P

6. p+p+p+p+p+p+5+1+1

6

Step-by-step explanation:

because the equation above says p+p+p+p+p+p+5+1+1

so if we add up the p's it will give us 6p and if we add up the nos it will give us 6p+7

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
