Answer:

  13.636

Step-by-step explanation:

The area can be found using Heron's formula:

  A = √(s(s-a)(s-b)(s-c))

where s=(a+b+c)/2.

For the given triangle, ...

  a=9, b=4, c=12, s=(9+4+12)/2 = 12.5

  A = √(12.5(3.5)(8.5)(0.5)) = √185.9375 ≈ 13.636

The area of the triangle is about 13.636 square units.

How can you use distributive property to find 3/4 times 2 and 1/3
zubka84 [21]

Answer:

1 3/4

Step-by-step explanation:

You can set it up like the distrubtive property first

3/4(2+ 1/3)    Next you use the distirbutive property instead of adding inside the parenthesis and you multiply the 3/4 by 2 and then the 3/4 by 1/3

Use 2 as 2/1 in fraction problems

3/4 * 2/1        Now multiply the numerators together and the denomenators together

3 * 2 = 6          4 * 1 =4

6/4

3/4 *1/3

3 * 1 =3

4 * 3 =12

3/12

Now we have to make them both like terms (same denominator) so we can add them, we will multiply the 6/4 by 3 (Both top and bottom)

6 * 3 = 18               4 *3 =12

18/12

Now we add the fractions

3/12 +18/12 = 21/12

Reduce that and you get

21/12 = 1 9/12  or 1 3/4
