Find the length of the missing side of the triangle

1 answer:

7 0

It is a right triangle, so we can use pythagorean theorem which states

a^2 + b^2 = c^2

Leg^2 + Leg^2 = Hypotenuse^2

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 144

x=12

Julia has 14 butterfly stickers. Daria has 26 butterfly stickers. How many more butterfly stickers does Daria have than Julia?

Leno4ka [110]

Answer:

12
B: additive comparison

Step-by-step explanation:

The word "more" in this context means we want to find the difference between the number Daria has and the number Julia has. It is an "additive" comparison.

____

You need to be a little careful with this. You will often see wording such as "... times more than ...", in which case it is a multiplicative comparison. (I would prefer the multiplicative comparison wording to be "... times as many as ...", so that "more" is reserved for additive comparisons. Alas, not in this lifetime.)
