Range: 7
rewrite the equation set = to 0.
x^2 + 5x - 8 = 0
The quadratic will not factor so you have to use the quadratic formula.
x = (-b + - sqrt(b^2 - 4ac))/2a
x = (5 + - sqrt(25 - 4* 1* -8))/2
x = (5 + - sqrt 57)/2
The x2is not the same as 2x. It is x^2. X tot he second power which makes the problem a quadratic equation. You cannot combine the terms x^2 and -5x because they so not have the same power.
Rationalizing is just simpllifying, so the simplified value has the same value as the original expression.
Answer:
5 apples
Step-by-step explanation:
First, we must find the cost of one apple
12/20 = the cost of one apple
= $0.60
Then, we divide 3 by the price of one apple
3/0.6 = amount of apple we can buy
= 5
Answer:
Step-by-step explanation:
