This situation calls for an observational study. Unfortunately, cardiovascular health is difficult to measure unless one defines some "health scale" so that health could be roughly quantitized.
Answer:
The common denominator is 100 because they dont have a number lower so 20*5 is 100 and 25*4 gives you 100
Step-by-step explanation:
2 triangular bases and three rectangular lateral faces
Think about the rule when multiplying powers together.
When multiplying two powers that have the
same base, simply add their exponents.
In this problem, each power has a base
of <em>a</em> and our exponents are <em>m </em>and <em>n</em>.
So adding these exponents together, we have a^m + n.
