The answer <span>5 was added to each side.
</span>
x² + 5x + 126 = x² + 17x + 66
____
Subtract x² from both sides:
x² + 5x + 126 - x² = x² + 17x + 66 - x²
5x + 126 = 17x + 66
126 - 66 = 17x - 5x
60 = 12x
x = 60/12
x = 5
Thus, <span>5 was added to each side.</span>
Answer:
78/100
Step-by-step explanation:
Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal
Answer:
ln ab^2
ln a + 2 ln b
ln a^2 + ln b^2 - ln a.
Step-by-step explanation:
2 ln a + 2 ln b - ln a
= ln a^2 + ln b^2 - ln a
= ln (a^2/a) + ln b^2
= ln a + 2 ln b
= ln a + ln b^2
= ln ab^2.
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is x
the sum of the 2 angles = 180°, hence
x + x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and x = 72°
Assuming that the number you are attempting to write is 5 8/5, you're whole number would be 6 3/5.
However, if the number is actually 58/5, then the whole number would be 11 3/5.
Here's how to find the answer:
For 5 8/5, you must find how many times 5 goes into the numerator since 5/5 is one whole number. However, there will sometimes be remainders as presented in this question, thus leaving you with another fraction which is 3/5.
Hope this helps!
