Tina used 10 1/2 yards of yarn to make three yarn dolls. She used 3 1/2 yards of yarn for the first doll and 4 1/7yards for the second doll. How much yarn did Tina use for the third doll?

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.

if you was gonna solve for a, a is a   < -12
