Cindy used 17.25 because 15 × .5 = 2.25 and if you add it to 15 ypu get 17.25
Answer:
Well you divide the total of 1.95/5
.39 cent
Answer:
The question says area of a square = 9 cm squared.
And they said if the sides are doubled in length what is the new length
so new length = 9 cm^2 × 9 cm^2
which should give you 81cm^2
therefore your answer should be = C
Multiply 14 to each term: 14a+70+84b
