"ann needs 42 feet of fabric to make a small quilt. how many yards of fabric should she buy? "

! thx

14 yards because 1 yard= 3 feet. 42/3=14. :) Hope this helps!

Ok, 3 feet are in a yard, a yard is 36 in total, 1 foot is 12 hopefully you know that, 12+12+12=36 .   42 feet goes into 3, 14 times  36 multiplied by 14 equals 504. Check 504 divided by 14 equal 36in so she needs 14 yards of fabric total.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
