Which equation can be used to calculate the area of the shaded triangle in the figure below? A rectangle with length of 12 feet and width 4 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded. (5 points) 2(12 + 4) = 32 fraction 1 over 2 (12 + 4) = 8 2(12 × 4) = 96 fraction 1 over 2 (12 × 4) = 24

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6
