A triangle has a base of 12 and one-third centimeters and height of 3 centimeters. Which expression could be used to determine the area of the triangle shown? One-half + 12 and one-third + 3 One-half (3) (12) (one-third) 12 and one-third times 3 One-half (12 and one-third) (3)

One-half (3) (12) (one-third)

Step-by-step explanation:

Area of a triangle bus expressed as shown.

Area of a triangle = 1/2bh

B is the base

H is the height

Given base = 12 1/3xm

Height =3cm

Area =>1/2 (3) 12(1/3)

Area = One-half (3) (12) (one-third)

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
