The first is a. you can rewrite it
the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined
the third is c.
the fourth is d.
add 3 to both sides
then square both sides
then divide both sides by 2, x=50

In this question, it is given that
Marcus bought pumpkins that weigh 8 lb, 11 lb, 23 lb, and 15 lb.
And we have to find the mean weight .
To find the mean weight, we will first add all the weights, then divide them by number of pumpkins which is 4.
So the mean weight is
Therefore the mean weight is 14.25 lb .
