.
Number of Rose's for 24 red Rose's = 6
This can be written in a ratio as 24:6
Number of roses = 8
Let the number of red roses for these roses be x.
Which means :
▪︎Therefore, 32 red roses are there if there are 8 roses.
<h2>○=> <u>Solution (9)</u> :</h2>Number of children for 2 adults = 7
This can be written in a ratio as 7:2

<h2>○=> <u>Solution (10)</u> :</h2>Cost of 12 pencils = P60
Cost of 1 pencil :
Thus, the cost of one pencil = P5
Cost of 25 pencils :
= Cost of one pencil × 25
▪︎Therefore, the cost of 25 pencils = P125
Use the rational zero theorem
In rational zero theorem, the rational zeros of the form +-p/q
where p is the factors of constant
and q is the factors of leading coefficient
In our f(x), constant is 2 and leading coefficient is 14
Factors of 2 are 1, 2
Factors of 14 are 1,2, 7, 14
Rational zeros of the form +-p/q are
Now we separate the factors
We ignore the zeros that are repeating
Option A is correct
