<span>4n+22=70
4n = 70 - 22
4n = 48
n = 12
value for 3n
3n = 3(12) = 36

Answer:
<u><em>(x+5) is not a factor of f(x)</em></u>
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
-4 1/2 = -4.5
5.6 = 5.6
-2 3/8 = -2.375
1.35 = 1.35
If we order it from least to greatest, we would get:
-4 1/2, -2 3/8, 1.35, 5.6
If we order it from greatest to least, we would get:
5,6, 1.35, -2 3/8, -4 1/2
(28 * x) -42 = 154
28x - 42 = 154
28x = 196
the unknown number is 7
Answer:
45
---------
(2 - x)
Step-by-step explanation:
That would be:
45
---------
(2 - x)
Also valid: 45/(2 - x)
