Answer:

f(8)=-31

Step-by-step explanation:

since 8 replaces x in f(x), x should be substituted as 8 in the expression. From there, after you substitute, it becomes 6(1-8)+11. Simplifying that expression is now 6(-7)+11. Multiply 6 and -7, you get -42. -42+11=-31. I hope this helps :)

Answer:

7 + 6

5 + 11

Step-by-step explanation:

the lengths of the two shorter sides of a triangle must add up to more than the length of the third side.

3 + 4 = 7 ≤ 8 no

7 + 6 = 13 > 12 yes

5 + 11 = 16 > 13 yes

4 + 6 = 10 ≤ 12 no

4 + 6 = 10 ≤ 10 no

Answer:

x = 58 degrees

Step-by-step explanation:

Angle K (which is x) and Angle I are congruent corresponding angles with one another, so if, as an example, Angle I was 10, Angle K would also be 10.

All you need to do in this case is add Angle H (56) and Angle A (66) together:

56 + 66 = 122

Then subtract 122 from 180 (because triangles add up to 180 degrees) to get x:

180 - 122 = 58
