10 POINTS What is the surface area of the Triangular Prism?
A) 230 units^2
B) 240 units^2
C) 250 units^2
D) 260 units^2

B

Step-by-step explanation:

third side of base=√(12²+5²)=√(144+25)=√169=13 units

surface area=area of three retangles+area of top and bottom

=(12+13+5)×6+2×1/2×12×5

=180+60

=240 units²

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
