26.) 3(2)² - 8(-3)²
= 3*4 - 8 + 9
= 12 - 8 + 9 = 13
27.) I 7 - 4(2) I
7 - 8 = -1, but since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.
28.) (-2)² + 2(-3 * 1)
= 4 + 2(-3)
= 4 + (-6) = 4 - 6 = -2
29.) 7(-4)² + 5 / 4(1) - (-5)
=7 * 16 + 5 / 4 + 5
= 112 + 5 / 9 = 117/9 = 13
30.) Product: the result of a multiplication problem
Increased by: multiplied by
3(n * 7)
31.) 2n - 1
Coordinate points on line(-3,-1) and (3,3)
Parallel lines have same slope
so
m = (3+1)/(3+3) = 4/6 = 2/3
Answer
B. 2/3
