Answer:
The answer is 2√15 .
Step-by-step explanation:
Using Indices Law :
Next, you have to find the common factors of 60 :
60 = 1×60
60 = 2×30
60 = 3×20
60 = 4×15
60 = 5×12
60 = 6×10
In order to simplify, we have to choose a perfect square from the factors above. In the factors above, 4 is a perfect square so that we can square root it :
Answer:
A. h(x)= -5.86x^2 + 23.37x + 34
Step-by-step explanation:
If the scientist uses the same amount of pesticide on the two farms then the x's of the functions are the same.
Then, the combined yield of the two farms is just the yield of the first farm plus the yield of the second farm:
.
Now, since
and
,
then
we add the coefficients of the corresponding terms to get:
Which is choice A.
