No, it's always okay to ask if you don't understand a question. Anyway, for this problem, we just have to plug in the value for <em>V </em>to solve for <em>P</em> :
A number to the power of 1/3 is the same as taking a cube root.
The perimeter of one face of the cube is 20m.
Answer:
2(x - 3)(x - 9)
Step-by-step explanation:
Given
f(x) = 2x² - 24x + 54 ← factor out 2 from each term
= 2(x² - 12x + 27) ← factor the quadratic
Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (- 12)
The factors are - 3 and - 9 , since
- 3 × - 9 = + 27 and - 3 - 9 = - 12 , thus
x² - 12x + 27 = (x - 3)(x - 9) and
f(x) = 2(x - 3)(x - 9) ← in factored form
Divisors maybe I'm not certainly for sure thou so don't

Answer:
Given 7b²-21b-273=7, the solutions are x1 = 8 and x2 = -5.
Step-by-step explanation:
Given 7b²-21b-273=7, first you need to equal zero. So
7b²-21b-273-7=0 ⇒ 7b²-21b-280 = 0
The secon step is to find the solutions applying Bhaskara´s formula x = (-b ± √(b²-4×a×c))/2×a
Where a=7, b= -21 and c= -280
After you identified each term, you have to replace it on the formula so....
x = (21 ± √(21² - 4×7×(-280)))/2×7 ⇒ x = (21 ± √(441 + 7840))/14 ⇒ x = (21 ± √8281)/14
Then you will obtain two values for x, called x1 = 8 and x2=-5.
