Can you help me? Thank you in advance! ​

D. 4 and -3/2

Step-by-step explanation:

Solve the equation for  y  by finding  a ,  b , and  c  of the quadratic then applying the quadratic formula.

formula: x = − b ± √ b ^2 − 4 a c /2 a

hope this helps!

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.
