What is the difference when 5x2 − 3x + 2 is subtracted from 4x2 − 7x + 9?

5-4x

Step-by-step explanation:

so when 10 - 3x + 2 is subtracted from 8 - 7x + 9

an important thing here is to remember the brackets as you minus something,

17 - 7x - ( 12 - 3x)

which gives 17 - 7x -12 + 3x

which then the difference yields 5 - 4x

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.
