1.1 Factoring: 4x2+9y2+16z2-6xy-12yz-8xz
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -6xy-12yz
Group 2: 16z2-8xz
Group 3: 4x2+9y2
Pull out from each group separately :
Group 1: (x+2z) • (-6y)
Group 2: (x-2z) • (-8z)
Group 3: (4x2+9y2) • (1)
Looking for common sub-expressions :
Group 1: (x+2z) • (-6y)
Group 3: (4x2+9y2) • (1)
Group 2: (x-2z) • (-8z)
Answer:
Step; This conversion of 10.03 kilometres to hectometres has been calculated by multiplying 10.03 kilometres by 10 and the result is 100.3 hectometres.-by-step explanation:
Answer:
Not a polygon
Step-by-step explanation:
[(3x+12)•(4x+4)]-(3x+8)-(4x)
[12x² + 12x + 48x + 48] - 3x - 8 - 4x
12x² + 60x + 48 - 7x - 8
12x² + 53x + 40
This is a degree 2 (quadratic) polynomial, not a polygon.
A polygon is an n-sided figure.
Example: A rectangle --> A four-sided polygon
The answer to this is 3.083
