When x = 3, then the expression:
8 x + 25 is written replacing the "x" with 3 in the implicit product times 8:
8 (3) + 25 = 24 + 25 = 49
So please select the last option among the possible answer (option D)
A second question states that if x = 14 and y = 6, evaluate the expression:
x - 7 + 4 y
So, as we did above, we replace the x and the y in the expression with the appropriate values:
(14) - 7 + 4 (6)
14 - 7 + 24 = 31
So please again select the Answer 31 from your options.
