Answer:
11 is 18.54 ft 12 is 351.86 cm 13 is 109.96 inches
Step-by-step explanation:
f(x) = 90(1.013)x
f(x) = 91.2(2.2)x
f(x) = 90(2.2)x
(x − 4)(x − 5)
(x − 2)(x − 10)
(x + 4)(x + 5)
(x + 2)(x + 10)
The factored form of the polynomial x² + 9x + 20 is ( x + 4 ) ( x + 5 )
Discriminant of quadratic equation ( ax² + bx + c = 0 ) could be calculated by using :
From the value of Discriminant , we know how many solutions the equation has by condition :
D < 0 → No Real Roots
D = 0 → One Real Root
D > 0 → Two Real Roots
Let us now tackle the problem!
Given :
To factor this form, we first look for the following operations:
_ + _ = 9
_ × _ = 20
To fill in the blanks, the matching numbers are :
4 + 5 = 9
4 × 5 = 20
Next, the above equation can be factorized into:

Answer:
(C)(x + 4)(x + 5)
Step-by-step explanation:
The given equation in the form of polynomial is:
Factorizing the above given equation, we get
Taking x+5 common, we have
which is the required factorised form.
Therefore the factors of the given polynomial are .
Thus, Option (C) is correct.
