Classify each expression as either equivalent or not equivalent to (15r)s+(6r-22t)

Question

There are two equivalent expressions.
• Equivalent
• Not Equivalent
-22t+(6r=15rs)
6r-(22t+15(rs))
(15r+6r)s-22t
15(rs+(-22t+6r)
(15s)r+(6t-22r)
Please answer all of it

Answer 1

-22t+(6r=15rs) : Not Equivalent (Uses "=" instead of "+")
6r-(22t+15(rs)) : Not Equivalent (Rearranges terms)
(15r+6r)s-22t : Not Equivalent (Rearranges terms)
15(rs+(-22t+6r) : Equivalent (Rearranges terms)
(15s)r+(6t-22r) : Equivalent (Rearranges terms)

Answer 2

Classify each equation below as either an equivalent or not equivalent rearrangement of the equation: p=1/2(a+b)h
There are two equivalent rearrangements.
• Equivalent
• Not Equivalent
2P=(a+b)h
H=a+b/2P
P=1/2ah+bh
2P/h=a+b
Please answer all of it

Answer 3

2P=(a+b)h : Equivalent (Rearranged by multiplying both sides by 2)
H=a+b/2P : Not Equivalent (Missing parentheses around (a+b))
P=1/2ah+bh : Equivalent (Rearranged by combining like terms)
2P/h=a+b : Not Equivalent (Missing parentheses around (a+b))
