The method of factorization is used to find the roots of a given polynomial. Roots are the solutions of the function. Graphically, these roots are where the curve passes the x-axis. The first step to do is to find the common factor of the equation. That would be x. So you place it outside of the parenthesis.
x³-4x²+45x = x(x² - 4x + 45)
If you solve the quadratic equation inside the parenthesis using the quadratic formula, the roots are imaginary. Therefore, the quadratic equation is already a prime polynomial.
The final answer is x(x² - 4x + 45).
C = d × pi
C = 6 × 3.14
C = 18.84
Let,
- Number of boys be 3x
- Number of girls be 2x
- Then, Total number of students = 3x + 2x = 5x
It is given that,
➙ Number of girls = 420
Then,
➙ 2x = 420
➙ x = 420/2 = 210
No. of boys = 3x = 630
Then,
➙ Number of students = 5x
➙ Number of students = 5(210)
➙ Number of students = 1050

Answer:
7boxes
Step-by-step explanation:
A box can hold a maximum of 8 cans
You have a total of 50 cans
The problem here is to determine the minimum number of boxes that can hold the 50 cans
Let the minimum number of boxes = y
The minimum required will be such that:
The Product of The number of cans X Number of Required boxes ≥50
8y≥50
y≥50/8
y≥6.25
Since a box have a fractional value, the minimum number of boxes required to store 50 cans will be the nearest whole number which in this case is 7.
