5k - 5 + 8f + 11 when k = 4 and f = 7

82

Step-by-step explanation:

5k - 5 + 8f + 11

5(4) - 5 + 8(7) + 11

20 - 5 + 56 + 11

15 + 56 + 11

71 + 11

82

82

Step-by-step explanation:

We have the expression and the variables and are being asked to solve.

We know that k = 4 and f = 7. So substitute :

5(4) - 5 + 8(7) + 11

20 - 5 + 56 + 11

15 + 56 + 11

71 + 11

82

its 8

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.
