Cheryl thinks that the following expressions are
equivalent:
3x + 3 = 3 + 3x + 0
Is Cheryl right? If so,
prove that these two
expressions are
equivalent. If not, what
error(s) did Cheryl make?

yes she is right

Step-by-step explanation:3x + 3 is the same as 3 + 3x.  

the zero adds nothing to the 3x term. So this means that 3x +3 and 3 + 3 are the same.

i hope this helps you.

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
