Answer:
1) a
2) c
3) a
Step-by-step explanation:
1) Subsitute
2.14x - 42.9 = ?
2.14(22.4) - 42.9 = ?
47.936 - 42.9 = ?
= 5.036
2) Factor out
6y^2 + 27y
both have 3 and y in common so ...
3y(2y + 9)
3) Distribute
12m(m - 3n)
12m * m = 12m^2
12m * -3n = -36mn the only reason -3 is NOT a positive is b/c it has subtraction sign b4 the number
put it in order:
12m^2 - 36mn
