Please help me with number 2 and threee

2.

3. =

30 and 5 are viable factors for 150

30 breaks down into 5 and 6

There are two 5s left and one 6.

So, the two fives go on the outside of the radical while the 6 goes on inside.

Therefore, it would be 5

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
