Given h (t) = negative 2 (t + 5) squared + 4, find h (negative 8).
–334
–14
45
445

-14

Step-by-step explanation:

h(-8) = -2 ( -8 +5 )^2 + 4

       =  -2 ( -3)^2 + 4

        = -18 + 4

        = -14

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
