Answer:
Step-by-step explanation:
is 2.65 rounded to the nearest hundrendth.
is 5.
is 6.48 rounded to the nearest hundrendth.
The factored form of this expression is (x+3)(x-3)(x-6)
<h3>Factored form of an expression</h3>
Given the polynomial function
x^3-6x^2-9x+54
Group
(x^3-6x^2)-(9x+54)
Factor out the greatest common factor
x^2(x-6) - 9(x- 6)
Find the factors
(x^2-9)(x-6)
using the difference of two square
(x+3)(x-3)(x-6)
Hence the factored form of this expression is (x+3)(x-3)(x-6)

Answer:
D- (0.4) (1,6) (2,8)
Step-by-step explanation:
The first thing we want to do is to make the equation a function, so we put y by itself on one side,
Add 4 to both sides
y = 2x + 4 <<< This is the equation that we will use
So if we input these numbers in,
The answer seems to be D. Where if x = 0 then y = 4 and so on

The two numbers I will call x and y.
x + y = 31
x * y = 150
You then solve for one variable in either equation and substitute it into the other equation.
x + y = 31
x = 31 - y
Then you plug it in:
x * y = 150
(31 - y) * y = 150
-y² + 31y = 150
y² - 31y + 150 = 0 Then factor:
(y - 6)(y - 25) = 0
y - 6 = 0 y - 25 = 0
y = 6 y = 25
When you plug y into the original equations, it comes out that the two numbers are 6 and 25. You can check your work because 6+25 = 31 and 6*25 = 150. Hope this helps! :)
