Answer:
Option A.,
Step-by-step explanation:
(5x3− x + 14) − (3x2− 9x + 4)
First remove the 2 sets of parentheses. Note when we remove the second one we multiply the terms inside by -1. ( Or we might say we distribute the negative over this parentheses.)
= 5x^3 - x + 14 - 3x^2 + 9x - 4
Now we simplify like terms:-
= 5x^3 - 3x^2 + 8x + 10 (answer).
16 6th graders went on the field trip and 16 5th graders went on the field trip so that makes 32 students all together which means 32% of the students went on the field trip
