The answer would be a) 14 sqrt 6
Check the picture below.
make sure your calculator is in Degree mode.
Bookshelf =7boards each
Lumber=4 boards each
He wants to make 5 bookshelves total
5x7=35
So he needs 35 boards
And each lumber makes 4 boards
So what number times 4 is equal to or more than 35?
9times 4 is 36
So he needs 9 pieces of lumber to make 5 bookshelves.
Good luck with your work! Brainliest would be appreciated :)
Let's have a look:
2(4)= 8 (this would not work)
5(4)= 20 (this wouldn't work)
7(4)= 28 This does, let's check the others.
7(6)= 42 This does not work.
"D" would be the correct answer.
I hope this helps!
