Answer:
The answers are:
a)
is FALSE.
b)
is TRUE.
c)
is FALSE.
d)
is FALSE.
e)
is FALSE.
f)
is TRUE.
g)
is FALSE.
h)
is FALSE.
Step-by-step explanation:
We can show that the FALSE statement are, in fact, false finding an example where the equality fails.
a) Take x=2 and y=3 and notice that (2+3)² = 25, while 2²+3²=4+9=13.
b) (x+y)² = (x+y)(x+y)=x²+xy+xy+y² = x² +2xy +y².
c) Take x=2 and y=3 and notice that 2/(2+3) = 2/5 which is different from 1/3.
d) Take x=2 and y=3 and notice that 2-(2+3) = 2-5=-3 which is different from 3. Recall that x-(x+y) = x-x-y=-y.
e) Take x=-2, and notice that [tax]\sqrt{(-2)^2} = \sqrt{4} = 2[/tex] which is different from -2.
f) The previous example illustrate why this is true.
g) Take x=1, and notice that
which is different from 3.
h) Take x=2 and y=3 and notice that 1/(2+3)=1/5 and 1/3+1/2 = 5/6.
Answer:
Minimum: (2,4)

Answer:
360
Step-by-step explanation:
The sum of the exterior angles of a regular polygon, irrespective of the number of sides is 360 degrees. If N is the number of sides, each exterior angle will be 360/N degrees. In the present case there 5 sides in a regular pentagon, hence each exterior = 360/5 or 72 degrees.
Answer:
188
Step-by-step explanation:
88 + 6= 94
94 + 94 = 188
188 divided by 2 = 94
94 - 6 = 88
88 was how much Paula paid
