the estimates or correct answer is 24/5 =4 4/5
Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: f(x) = x^2 and g(x) = (3x)^2.
g(x) can be rewritten as 9x^2.
The graph of g(x) is only one ninth as wide as that of f(x).
Next time please share the possible answer choices. Thank you.
The quadratic formula is above.
You want each equation in standard form: ax^2 + bx + c = 0
I begin each problem by defining variables.
For instance 3. Is in standard form. X^2 -2x - 3 = 0. a = 1, b = -2, c = -3
Now use quadratic formula: x = [- b + or - sqrt(b^2 - 4ac)]\2a
The answer to your question is c 55
