Answer:
it is 5 to figure 9 you move 8 units and 2 units
Answer:
12
Step-by-step explanation:
using pythagoras theorem
here 15 is hypotenuse since it is opposite 0f 90 degree
9 and x are the other smaller sides of a triangle
according to pythagoras thorem the sum of square of two smaller sides of a triangle is equal to the square of hypotenuse. So,
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 225 - 81
x^2 = 144
x =
x = 12
(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.
Answer:
y = - 9x + 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 9x - 2 ← is in slope- intercept form
with slope m = - 9
Parallel lines have equal slopes, thus
y = - 9x + c ← is the partial equation
To find c substitute (2, - 3) into the partial equation
- 3 = - 18 + c ⇒ c = - 3 + 18 = 15
y = - 9x + 15 ← equation of parallel line
