Answer:
2x(x + 5)(x - 2y)
Step-by-step explanation:
a) 2x³ + 10x² - 4x²y - 20xy
The greatest factor among the expression is the greatest factor common to each term in the expression. From the expression, each of the terms has a factor of 2x, hence the greatest common factor is 2x, therefore:
2x³ + 10x² - 4x²y - 20xy = 2x(x² + 5x - 2xy - 10y)
b) 2x³ + 10x² - 4x²y - 20xy = 2x(x² + 5x - 2xy - 10y)
= 2x[x(x + 5) -2y(x + 5)]
= 2x(x - 2y)(x + 5)
= 2x(x + 5)(x - 2y)
2x³ + 10x² - 4x²y - 20xy = 2x(x + 5)(x - 2y)

Answer:
2x − 5x + 11
Step-by-step explanation:
Assuming this Fence enclosment will be in the shape of a rectangle we will use the equation used to find the area of a rectangle, b×h=a
Using this formula we then must pick out factors used to create, in which the perimeter will add up to 60
·1,29,1,29 (29)
·2,28,2,28 (56)
·3,27,3,27 (81)
·4,26,4,26 (104)
·5,25,5,25 (125)
·6,24,6,24 (144)
·7,23,7,23 (161)
·8,22,8,22 (176)
·9,21,9,21 (189)
·10,20,10,20 (200)
·11,19,11,19 (209)
·12,18,12,18 (216)
·13,17,13,17 (221)
·14,16,14,16 (224)
·15,15,15,15 (225)
using this we can learn<span> that the maximum area that can be exclosed by this is 225, because the 2 perimeter lengths that define this rectangle would be 15 and 15.
</span>b(15)×h(15)=225(a)
therefore, your answer is 225 Units
