Answer:
28
Step-by-step explanation:
Answer:
x = 15/11
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
(x+3) *x = 2x*(6x-6)
Divide each side by x
x+3 = 2(6x-6)
Distribute
x+3 = 12x-12
Subtract x from each side
x+3-x = 12x-x-12
3 = 11x-12
Add 12 to each side
3+12 = 11x-12+12
15 = 11x
Divide each side by 11
15/11 =x
Answer:
756 ways
Step-by-step explanation:
Given
Required
Determine the number of ways
The first counter can be selected in 28 ways
The second can be selected in (28 - 1) ways
The number of selection is:
<em>Hence, number of possible selection is 756</em>
Answer:
1) -4<x<0 = (-4,0)
2) x>=0 = [0, infinity)
3) 0<x<4 = (0,4)
4) -4<x<=4 = (-4,4]
5) x<=0 = (-infinity,0]
Step-by-step explanation:
Basically, we need to link inequalities with their solutions.
1) -4<x<0: solution to this inequality are all numbers between -4 and 0, or mathematically written (-4,0).
2) x>=0: solution to this are all numbers between 0 (including 0) and positive infinity, or [0, infinity)
3) 0<x<4: all numbers between 0 and 4, or in interval notation (0,4)
4) -4<x<=4: all numbers between -4 and 4 (including 4) which in interval notation is (-4,4]
5) x<=0: all the values from negative infinity to 0 (including 0), which is (- infinity,0]
Note that whenever there is symbol <= or >= we also need to include that value, and for noting that we use square bracket.
