Answer:
1 +√21 + 1 - √21
2 2
Step-by-step explanation:
1/12 ÷30 is equal to 1/360 or in decimal form is a repetitive decimal which is .2777777777777777777777....
Because like terms you add or subtract together to make it easier to do the problem. just like you do with whole numbers. you add an subtract to make the answer simpler.
Answer:
slope of n =⅔
Step-by-step explanation:
The product of the slope of two perpendicular lines(m1•m2) must equal -1.
This means that if you have the slope of one line,find it's negative reciprocal to obtain the slope of the other.
Thus,-1/(-3/2)=⅔
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
