Question

17. Evaluate the expression when x = 2, y = -3, and z = -1 2x + 3y - z A. 4 B. 14 C. 5 D. -4 18. 25x^2 - 36 A. (25x + 1)(x - 36) B. (5x - 6)^2 C. (5x + 6)^2 D. (5x - 6)(5x + 6)

SnapAndSolve AI · Accepted Answer

Substitute x = 2, y = -3, z = -1 into the expression 2x + 3y - z:

2(2) + 3(-3) - (-1) = 4 - 9 + 1 = -4

Answer: D. -4
Factor 25x^2 - 36:

This is a difference of squares: (5x)^2 - 6^2 = (5x - 6)(5x + 6)

Answer: D. (5x - 6)(5x + 6)
