2(x+4) = 1/2(4x-4)
Multiply through by 2:-
4(x + 4) = 4x - 4
4x + 16 = 4x - 4
4x - 4x = -4 - 16
0 = -20
This is obviously wrong so there is NO Solution (answer).
Answer:
second option
Step-by-step explanation:
Pythagoras for right-angled triangles :
c² = a² + b²
c is the Hypotenuse, the line opposite of the 90 degree angle.
a and b are the other 2 sides.
the distance between 2 points is the Hypotenuse of a right-angled triangle of the coordinate differences in x and y.
so, we have (-2, -3) and (3, 2)
distance² = (x1 - x2)² + (y1 - y2)² = (-2 - 3)² + (-3 - 2)² =
= (-5)² + (-5)² = 25 + 25 = 2×25 = 50
distance = sqrt(50) = sqrt(2×25) = 5×sqrt(2)
Hello,
if 0 is a positive integer
sum=0+1+...+59=(0+59)*60/2=59*30=1770
else
sum=1+2+3+...+60=(1+60)*60/2=61*30=1830
end if
Answer D: 1830
In US, 0 is not positive, in Europe yes!!!
Answer:
1800
Step-by-step explanation:
Since there is the tragon fly beat his wings 30 times a second ,there is 60 hundredths of a second in a second multiply 30 x 60 and you should get 1800.
- mulitiply 0x0 = 0
2. mulitiply 6x0=0
3. multiply 3x0=0
4. mulitiply 6x3 = 18
5. have 1800
or you can just multiply 6x3 = 18 and add the two zeros
