is the equation with consistent value.
Trinomial is the ancer to the first one
Which one is question 20??
Answer:
64 books
Step-by-step explanation:
The first step is to find the number of books that will fit in the shelve per foot
= 40/5
= 8

= 8×8
= 64
Hence 64 books would fit in 8-foot shelf
18) 36.36 rounded it is 36.4
22)53.71 rounded it it’s just 53.7
