Darnel's retirement party cost $33, plus an additional $1 for each guest he invites. What is the maximum number of guests there
Karolina [17]

Answer: the maximum number of guests that he can invite would be 9

Step-by-step explanation:

Darnel's retirement party cost $33, plus an additional $1 for each guest he invites. Assuming Darnel wants to invite x guests to his retirement party, the total amount of money that Darnel would spend is

33 + x

if darnel can afford to spend a total of $42 on his retirement party, then

42 = 33 + x

x = 42 - 33 = 9

What is the solución of the equation x2-4x+1=0?
koban [17]

Answer:

x = 2 + √3 and

x = 2 - √3

Step-by-step explanation:

Please use " ^ " to denote exponentiation:  x^2 - 4x + 1 = 0.

Here you have multiple choices of methods of solution:

quadratic formula, completing the square, graphing, and so on.

If we complete the square, then:                   x^2 - 4x + 1 = 0 becomes

                                                                       x^2 - 4x + 4 - 4 + 1 = 0, or

(x - 2)^2 = 3

Taking the square root of both sides, we get x - 2 = ±√3, so that the roots are:

x = 2 + √3 and

x = 2 - √3

What mathematical pattern can be seen in a perfect square trinomial and how is the pattern used to factor the trinomi
Shtirlitz [24]
(a ± b)² = a² ± 2ab + b² . . . . . . . (signs match)

The middle term is twice the product of the roots of the other two terms. This tells you the terms of the binomial are the square roots of the end terms.

The sign in the binomial will match the sign of the "2ab" term. The order of terms in the binomial doesn't matter. (a±b)² = (b±a)² when signs match.
