Answer:
Step-by-step explanation:
since there are 205 calories in 5 crackers we can represent this as
205/5
we need to find how many calories are in one cracker, so lets take "x" as the # of calories in 1 cracker
so
cross multiply
5x=205
divide by 5 on both sides
x=41
41 calories in 1 cracker
Number line:
x² + 50
= x² - (-50)
= Side note:
= (x + 5i)(x - 5i)
