Alright. For the first one, we must think, thirty percent of what number is equal to twelve? We can right that in equation form as
Answer:
(7,2)45 units sqrd
Step-by-step explanation:
45 units sqrd because its a 5x9
Answer: 9 tilapia
Step-by-step explanation:
The ratio of 6:20 for tilapia to catfish means that for every six tilapia, there are 20 catfish in the pond.
If there are 30 catfish, use direct proportion to find out the number of tilapia:
6 : 20
x : 30
Cross multiply:
20x = 180
x = 180 / 20
x = 9 tilapia
Step-by-step explanation:
7(36-2c+4)
=252 - 14c + 28
=310 - 14c
Answer:
All potential roots are 3,3 and
.
Step-by-step explanation:
Potential roots of the polynomial is all possible roots of f(x).

Using rational root theorem test. We will find all the possible or potential roots of the polynomial.
p=All the positive/negative factors of 45
q=All the positive/negative factors of 3


All possible roots

Now we check each rational root and see which are possible roots for given function.




Similarly, we will check for all value of p/q and we get

Thus, All potential roots are 3,3 and
.
