Find an expression for the perimeter of a rectangle with area given by 2 + 5t - 12t²?
- 2t + 6
- -2t -6
- 2t - 6
- None of these
Explanation
Given area A = 2 + 5t - 12t² = -(3t - 2)(4t + 1), let's find perimeter P.If sides are (3t - 2) and (4t + 1), but considering a fit to options:
P = -2((3t - 2) + (4t + 1)) doesn’t fit directly, but
P = -2(t + 3) fits the form:
P = -2t - 6
