Answer: 17. is A and 18 is most likely G
Step-by-step explanation:
Her statement is possible, the first rectangle could be equal to the second because x is unknown so if x was 5in in the first rectangle and - 1 in the second rectangle both problems would look like this 2 in & 5 in and the second one 5in & (2 in = (-1 +3)).
The answer is $2.35
if u add $1.25 and $2.35 you get $3.60
