(10 points and brainliest)
which expression is represented by the model below?

a.-7 + (-5)

b.-7 + (-2)

c.-7 + 0

d.-7 + 5

The lower arrow points to the left (negative direction)and goes from 0 to -7, so the first number is -7

The top arrow points to the right ( positive direction) and goes from -7 to -2, which is 5 units.

The answer would be D.-7 + 5

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.
