Problem 3.1 - enhanced - with feedback you may want to review ( pages 65 - 67) . part a draw the vector d⃗ =a⃗ +b⃗ . the location and orientation of the vector will be graded. the length of the vector will not be graded.

2.56 is the width of the garden

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:
