 -4 1/4 - (-9 1/2).....distribute the negative thru the parenthesis
-4 1/4 + 9 1/2 .....turn to improper fractions
- 17/4 + 19/2...common denominator is 4
-17/4 + 38/4 ....when ur dealing with 2 different signs, u subtract and take the sign of the largest number
-17/4 + 38/4 = 21/4...turn to mixed number = 5 1/4

OR
once u get to -4 1/4 + 9 1/2...turn to decimals
-4 1/4 = -4.25
9 1/2 = 9.5

-4.25 + 9.5 = 5.25 which equals 5 1/4

PYTHAGOREAN THEORM PLEASE HELP ME
madreJ [45]

Answer:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.

Step-by-step explanation:

Yes.

The first has an area of 9, so each side is three.

The second has an area of 16, so each side is four.

Each side of the third square is given as 5.

So the triangle has sides of 3, 4, and 5.

3²+4²=5²

9+16=25

25=25 It works given the Pythagorean theorem.
