nswer:
209.8
Step-by-step explanation:
the bottom is = 11 * 5
two of the sides are 11 * 9.3 / 2    because they are triangles, and then times 2 because there are two of them
the other two sides are 10.5 * 5 / 2 , and the * 2 because there are two of them again.
(11 * 5) + (11 * 9.3 * 2 / 2) + (10.5 * 5 * 2 / 2) =209.8

Answer:
46 and 277
Step-by-step explanation:
Given
f(x) =  - 8x - 11 ← substitute x = 3, x = - 4 into f(x)
 - 8x - 11 ← substitute x = 3, x = - 4 into f(x)
f(3) =  - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
 - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
f(- 4) =  - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277
 - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277
