Let b = width
l = length
Then, l = 2b - 2 ----------(i)
and, Perimeter = 86 cm
=> 2(l+b) = 86
=> 2b - 2 + b = 86/2
=> 3b = 43 +2
=> b = 45/3 = 15
=> b = 15
Putting the value of b in equation(i)
And, l = 2×15 - 2
= 30-2
= 28
Hence, length = 28 cm
width = 15 cm

Factor COMPLETELY the expression 2x^3 - 250
AURORKA [14]

Answer:

2 (x - 5) (x^2 + 5 x + 25)

Step-by-step explanation:

Factor the following:

2 x^3 - 250

Factor 2 out of 2 x^3 - 250:

2 (x^3 - 125)

x^3 - 125 = x^3 - 5^3:

2 (x^3 - 5^3)

Factor the difference of two cubes. x^3 - 5^3 = (x - 5) (x^2 + x 5 + 5^2):

2 (x - 5) (x^2 + 5 x + 5^2)

5^2 = 25:

Answer: 2 (x - 5) (x^2 + 5 x + 25)
