A polynomial with three terms is called a trinomial. Trinomials often but not always! have the form x2 + bx + c. At first glance, it may seem difficult to factor trinomials, but you can take advantage of some interesting mathematical patterns to factor even the most difficult-looking trinomials.
It’s a lot but hopefully I help:)

X = 5 and y = -12 is in the fourth quadrant. Hypotenuse = 13
sin theta = opposite / hypotenuse = -12 /13
Answer:
Employee's pay before rise was $19.25.
Step-by-step explanation:
It is given in the question that an employee earns $20.79 per hour after receiving 8% rise and we have to calculate employee's hourly pay before rise.
So to solve this let's assume employee's hourly pay before rise was $a
Then after raise the salary will be = $a + 8% of $a
= a + (a×
Now a+(.08)a = 20.79
⇒ 1.08a = 20.79
⇒ a = 20.79÷1.08
⇒ a = $19.25
So employee's hourly pay before rise was $19.25.
Answer:
Part a) Exactly values
The width of the rectangle is
The length of the rectangle is
Part b) Approximately values
The width of the rectangle is
The length of the rectangle is
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The area of rectangle is equal to
we have
substitute the values in the formula
so
Solve for x
Divide by 4 both sides
square root both sides
The solution is the positive value
therefore
<em>Exactly values</em>
<em>Approximately values</em>
