3/10 , 30% , 0.3 depends what they want the answer in but they all are the same just different answer forms .
Answer:
The equivalent factored form of this equation is (x² + 49)(x - 6)
Step-by-step explanation:
<em>x³ - 6x² + 49x - 294</em>
First, group the first and second terms together and group the last two terms together.
<em>(x³ - 6x²) + (49x - 294)</em>
Find the greatest common factor of both parentheses and factor them.
x²(x - 6) + 49(x - 6)
Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.
So, the factored form of the equation is (x² + 49)(x - 6)
To find the mean, we add up all the numbers then divide the sum by how many numbers there are
12 + 15 + 14 + 12 + 4 + 8 = 65
65 ÷ 6 = 10.833333
Hope this helps
Answer:
Step-by-step explanation:
You have this expression:
You already know that the value of the variable "x" is:
And the value of the variable "y" is:
Therefore, you can substitute the value of the variable "x" and the value of the variable "y" into the expression.
Then you get:
Answer:
x=40
Step-by-step explanation:
80°+(2x+20)°= 180°... (co-interior angles are supplementary)
2x=180 - 80 - 20
2x=80
(divide both sides by the coefficient of x which is 2)
x=80÷2
x=40
Check:
(2x+20) must be equal to 100
Let x=40
Therefore :
2X40+20
=100
