Answer:

24x + 60 = 540

x = 20

Step-by-step explanation:

67 + 7x + 7x + 4x-4 + 6x-3 = 540

24x + 60 = 540

24x = 480

How to Simplify (x-2)(3x2 + 3x + 2) to a polynomial in standard form:
swat32
Answer: 3x^3 - 3x^2 - 4x - 4

Explanation:

(x - 2)(3x^2 + 3x + 2)

= x(3x^2 + 3x + 2) - 2(3x^2 + 3x + 2)

= 3x^3 + 3x^2 + 2x - 6x^2 - 6x - 4

= 3x^3 - 3x^2 - 4x - 4

How to find maximum and minimum values of a parabola
Arturiano [62]

Answer:

Step-by-step explanation:

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

Solve for x. Round to the nearest tenth, if necessary.
Sphinxa [80]

Answer:

2.8

Step-by-step explanation:

tan = opposite / adjacent

( opposite = side opposite of the angle and adjacent = side length that is not the opposite nor the hypotenuse ( longest side ) )

we are given an angle, ∠E = 26°

tanE = x / 5.7

tan26 = x / 5.7

==> multiply both sides by 5.7

5.7tan26 = x

==> simplify

x = 2.8 ( rounded )
