Answer:

Her first error was adding the wrong number to both sides. Instead of 4², it should be 2²

Step-by-step explanation:

When completing the square, the number that needs to be added to both sides is (b/2)²

In this problem, b is 4. So, Carly should have added 2² to both sides, but she added 4² instead.

So, her first error was adding 4² to both sides instead of 2²

Solve these arithmetic: 2.75+0.003+0.158 =
olganol [36]
First, let's add 2.75 + 0.158.  First, we add the thousandths places.  Now, we have 2.758 + 0.15.  Next, let's add the hundredths place.  This is equal to 2.808+0.1.  Finally, we have the tenths place.  Now, our number is 2.908.

To finish this problem, we add 0.003.  2.908 + 0.003 = 2.911, so 2.911 is the answer to this problem.
