Answer:
x = 5
Step-by-step explanation:
The interior angles of a triangle <em>always</em> have to add up to 180 degrees.
This means you can form an equation with the three angles you have:
(10x - 4) + (8x + 3) + 91 = 180
Then, solve:
combine like terms
subtract 90 from both sides
divide both sides by 18
Answer:
Step-by-step explanation:
The given quadratic expression is
3x² - 9x + 6
Dividing each term in the expression by 3 in order to simplify it further, it becomes
x² - 3x + 2 = 0
We would determine two numbers such that their sum or difference is -3x and their product is 2x².
The two numbers are - 2x and - x.
Therefore,
x² - 2x - x + 2
x(x - 2) - 1(x - 2)
(x - 1)(x - 2)
When the expression is factored completely, it is equivalent to
(x - 1)(x - 2)
