Which set of side lengths form a right triangle?

1 answer:

4 0

Since we don't want to use the Pythagorean Theorem on all of these, first we look for some Pythagorean Triples. Its very helpful to know some of the common ones, so here's a list:

3, 4, 5
5, 12, 13
7, 24, 25
8, 15, 17

So we either look for these or a multiple of these numbers.

The last one is the only one that fits because 15, 20, 25 is a multiple of the triple 3, 4, 5 by multiplying all of them by 5.

Thus, 15, 20, 25 forms a right triangle.

Step-by-step explanation:

You are finding the whole

0.7 × 20 = 14

70% of 20 = 7/10 x 20 = 7/10 x 20/1 = 140/10

140/10

140/10 = 14/1

The minimum number of questions he need to do are 14

I'm not sure if you are finding the part or the whole

Find f (0) and find x when f (x) =4

Anuta_ua [19.1K]

At x = 0, y-coordinate is at -4 so that means f(0) = -4

Now for f(x) = 4, we need to find any x-coordinates such that y-coordinates is 4.

There are two possible answer: x = -8 and x = 8

So x = -8, 8

Hope this helps.
