A carpenter uses 65 shelves to make 13 bookcases. She uses the same number of shelves for each bookcase. How many shelves are used for each bookcase? (hint: 65 ÷ 13)
Are 32 shelves enough for 6 more bookcases? (yes or no)

First, we would need to figure out how many shelves are needed to build 1 bookcase. To do that, you would need to divide the number of shelves by the number of bookcases it can make.

65 ÷ 13 = 5

Now we know, it takes 5 shelves to build a single bookcase.  The next step would be to find out how many shelves it would take to build 6 more bookcases.  To find the answer, you would multiply the number of shelves it takes to build 1 bookcase by the number of bookcases that need to be built.

5 x 6 = 30

So, yes, 32 shelves would be more than enough to build 6 more bookcases.

w'x is 0.

hope it

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
