Answer:
Value of x using quadratic formula (x = -4) and (x = -5)
Step-by-step explanation:
Given:
Equation
x² + 9x + 20 = 0
Find:
Value of x using quadratic formula
Computation:
Quadratic formula = [-b±√b²-4ac] / 2a
Given equation;
x² + 9x + 20 = 0
a = 1 , b = 9 , c = 20
By putting value
[-9±√9²-4(1)(20)] / 2(1)
[-9±√81-80] / 2
[-9±√1] / 2
(-9 + 1) / 2 , (-9 - 1) / 2
-8 / 2 , 10 / 2
-4 , - 5
Value of x using quadratic formula (x = -4) and (x = -5)
Answer:
60
Step-by-step explanation:
60 plus 60 plus 60 is 180
has to add up to 180
About 260 because 202 plus 57 equals 259 and that'll round to 260
Answer:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Step-by-step explanation:
Given f(x) = 7x-5 and g(x)=2x-4, we form the quotient f/g as follows:
7x - 5 7x - 5
(f/g) = ----------------- = ----------------
2x - 4 2(x - 2)
Note that this is not defined for x - 2, due to division by zero.
