Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.

h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.

h(-8) = -2[9] + 4, multiply -2 and 9.

h(-8) = [-18] + 4, add -18 and 4.

h(-8) = -14.

Answer:  \textsf{Option A, 13}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{Side length = 9 units}

Find:  \textsf{Diagonal length}

Solution:  The diagonal length can be easily determined using an equation which uses the side length of a square multiplied by the square root of 2. All we need to do is plug in the values and simplify the expression.

<u>Plug in the values</u>

  • \textsf{Diagonal = Side length} * \sqrt{2}
  • \textsf{Diagonal = 9 units} * \sqrt{2}

<u>Simplify the expression</u>

  • \textsf{Diagonal = 9 units * 1.4142}
  • \textsf{Diagonal = 12.73 units}

Looking at the answer options that have been provided, the option that best fits our scenario is option A, 13.
