PLZ HELP IM ON A TIMER I WILL GIVE BRAINLIEST

Step-by-step explanation:

will be 3 or 4 because 9 x 2 is 18 plus 3x2 equals 24 and 12 x 2 is equal to 24 and -2 and negative -3 add those together and u have -5 so now your basically doing 24 - 5 y but idk how they do it in your lesson so its 3 or 4

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

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.
