Answer:
x+7
Step-by-step explanation:
Take the 28 and tern it into -28 and do it on both sides, -28 + 28 = 0, -28 + -1 = -30.
Sence x represents one aka any number you will add x with 11 and you will get 12x^2
Now you have to divide 12 on both sides, 12 divided by 12 is 1 so it eliminates it, 12 divided by -30 = -2.5, so then X = -2.5, and that should be right
I hope this helps! =)
Answer:
Step-by-step explanation:
A. 4.2E6 because when putting a number into scientific notation, you would want one number in front of the decimal place and then the trailing numbers would follow. The exponent or E stand for how many numbers are after the decimal, which in this case would be 6.
4,200,000 → 4.2 x 10^6 which is equal to saying 4.2E6
Tip: If the exponent is negative than the decimal would go in the opposite direction. For example:
4,200,000 → 4.2 x 10^-6 would not equal each other because 4.2 x 10^-6 means 0.000004, six numbers would be behind the decimal.
