<u>Quadratic Formula</u>
Given the second-degree equation:
The solutions of the equation can be obtained by applying the formula:
The equation to solve is:
Which means the values of the coefficients are: a=3, b=-7, c=-3. Substituting the values in the formula:
There are two real solutions for this equation:
The approximate values of both roots are:

Answer:
(d) -11
Step-by-step explanation:
The sum of the acute angles of a right triangle is 90°. (That makes the sum of all angles be 180°, as it is for any triangle.)
65° +(36 +x)° = 90°
x = 90 -101 . . . . . . . . divide by °, subtract 101
x = -11
Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
