3/5 + (- 4/15)

I got -1/15 but I have no idea if it's right​

Nope

Step-by-step explanation:

You must convert fractions to the same denominator

Convert 3/5 to 9/15

3/5 = 9/15

Then add the numerators together.

9/15 + -4/15 = 5/15

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

hello! just here for points! though i wish i knew!
