Mr. knotts found the difference of the following expression. which statement is true about mr. knotts's work?
x/x^2-1 -1/x-1

For this case we have the following expression:

To simplify we have:

Rewriting with the same denominator we have:

Thus, the simplified expression is:

add 5 subtract 1

step-by-step explanation:

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.
