Answer:
(3a+2)/a(a+2)
Explanation:
(1/a)+(2/(a+2)
we cannot add any unlike fractions simply,we have to make it's denominator equal to add
you can do it by simply multiplication or by taking lcm of the the denominator!
here , it's 'a' and 'a+2'
now we got a modified denominator a(a+2), to make it fair to each term we have to multiply the extra multiplicand to numerator too
in case of 1/a, denominator becomes a(a+2) ,so we have to modify numerator also by multiplying the extra (a+2) to numerator also ,now 1/a becomes (a+2)/a(a+2)
---- similarly other term={2/(a+2)}can be modified as 2a/a(a+2)
now both denominator are equal , now new can add it simply by it's numerator
i.e, (a+2)/a(a+2) + 2a/a(a+2)
= (3a+2)/a(a+2)
it's from basic of fraction's addition!

Answer:
Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.
Explanation:
the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.
Hope this helps!

Answer:
IF flowers are exposed to detergent, THEN the flowers will grow poorly
Explanation:
Hypothesis of an experiment gives a testable explanation to a problem. It is a predictive statement that explains the possible solution to a given problem, but subject to testing via experimentation. Hypothesis usually goes in an IF (cause), THEN (effect) format. That is, it shows how an independent variable will affect the deoendent variable.
In this experiment involving the effect of soap on flower growth, a possible hypothesis will be that: IF flowers are exposed to the detergent, THEN the flowers will grow poorly. This hypothesis, which is subject to testing by conducting an experiment, gives a possible solution to the problem of how detergent is affecting plant growth.
