Evaluate 5(a–b), if a=−4, b=−2

-10

Step-by-step explanation:

5(a–b)

Let a = -4 and b = -2

5(-4 - -2)

5(-4+2)

5(-2)

-10

  -10

Step-by-step explanation:

5( a - b)

5 ( -4 - -2)

5 ( -4 + 2)

5(-2)

-10

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.
