Answer: 17
Step-by-step explanation:
ANSWER
The correct answer is C.
EXPLANATION
The given polynomial has equation

According to the Remainnder Theorem, if (b+4) is a factor of p(b) = b³+3b²-b+12 then

We now substitute b=-4 to check.


Simplify:

Since p(-4) is zero, (b+4) is a factor of p(b) = b³+3b²-b+12.
The correct choice is C.
Given:
Ratio of cow to chicken is 6:5.
The nunmber of cows is 30.
The objective is to find the number of chickens.
Consider the number of cows and chicken as 6x and 5x.
The value of <em>x</em> can be calculated as,

Now, substitute the value of <em>x</em> to find the number of chicken.

Hence, the number of chicken will be 25.
Step-by-step explanation:
25x² - 16
= (5x)² - (4)²
= (5x + 4)(5x - 4).
