Answer:
Step-by-step explanation:
i cannot find an answer from the expression but i can guess if you didnt follow pemdas, it would be d
3.5 × 102 is 357
(8 × 10−4) + (6 × 10−4) is 132
132/357= .369 or .37 or 0 simplified
d is 4*10-10
10-10 is 0
4*0 is 0
Answer:
the answer is negative infinity to infinity since the range is -66 to infinity
To work it out:
(20200 + 14500 + 18800 + 9300 + 2200) divide by the number of regions, in this case 5.
The answer is 13000 which is A
Basically the mean is adding all the numbers divided by the amount of numbers you added. So in this case adding the data of the 5 regions divided by 5.
Hope to have helped :)
Using the distribution method:
x^2 + 12x - 8x = 14 + x^2 - 4x
x^2 + 4x = x^2 - 4x + 14
Now, I'm isolating x by moving all the x's onto one side of the equation:
x^2 - x^2 + 4x + 4x = 14
Combine like terms (x^2 cancels out):
8x = 14
x = 14/8
Simplified: x = 7/4
