question 20\n6 pts\nthe distance between the crest (highest point) of a wave and trough (lowest point) of a wave can be calculated by subtracting the trough from the crest. if the crest is 18 and the trough is -2, what is the distance?\n\nquestion 21\n6 pts
Answer
Explanation:
Step1: Set up subtraction
We need to subtract the value of the trough from the value of the crest. The formula is $crest - trough$. $18-(- 2)$
Step2: Simplify the subtraction
Subtracting a negative number is the same as adding its positive counterpart. So $18-(-2)=18 + 2$. $18+2 = 20$
Answer:
20
