Answer:
x = ± 
- 2
Step-by-step explanation:
x² + 4x = 4
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 4 + 4
(x + 2)² = 8 ( take square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = ± - 2
Answer:
the answer is 20%.
Step-by-step explanation:
all you have to do is multiply 42.50x.20 and it gives you 8.5. to check your answer you subtract 34.00 from 42.50 and you get 8.5 as well. hope this helps!
Multiply 4 by 10%.
10% ⇒ 0.1
4 × 0.1 = 0.4
Subtract 0.4 from 4.
4 - 0.4 = 3.6 (price with discount)
Multiply 3.6 by 6%.
6% ⇒ 0.06
3.6 × 0.06 = 0.216
Add 0.216 to 3.6.
0.216 + 3.6 = 3.816
Round 3.816 to the hundredths.
3.816 ⇒ 3.82 (price with tax)
The new price of toothbrushes is $3.82.
Use the distance formula. X 2 = 2 and X 1 = -2
Y 2 = 6 and Y 1 = -2
The answer should be 8.94
Hi there!
First let's multiply the fraction 1/4 x 3/3. This will give us all of the same denominators. Now, we have 6 3/12, 5 5/12, and 6 1/12. Since the lowest number is 5, we know that 5 5/12 is the smallest value. Then, we see that we have two 6's left. Since 3/12 is bigger than 1/12, we know that 6 1/12 comes after 5 5/12. Lastly, 6 3/12 is the greatest.
ORDER:
5 - 5/12, 6 - 1/12, 6 - 3/12
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
