Answer:
-√2
Step-by-step explanation:
x² - 2x = 8 Apply the square root to both sides
√x² - 2x = √8 Divide both sides by -2
x = -√2
<u><em>Extra info:</em></u>
√8 = 2√2 = 2.828427125
-√2 = -1.414213562
2x-10= 28
+10 +10
2x= 28
x=14
Answer: 12 weeks
Step-by-step explanation:
If Keith wants tgo have at least 200 in his account at the end of summer you need to minus it from the original 500 to make a new total.
Now you will have $300 to work with.
Since Keith needs $25 a week you will divide your new total ($300) by 25 and it will give you the number of weeks he can sustain this budget.
300/25=12
5.7^2 + 9.8^2 - 10.2^2 / 2*5.7*9.8 =
24.49/111.72 = 0.219 = 0.22
answer is 0.22
Answer: x = 7
Step-by-step explanation:
4(2x-3) = 6x+2 <--distribute the 4
8x - 12 = 6x + 2 <---add 12 to both sides
8x = 6x + 14 <--- subrtract 6x from both sides
2x = 14 <--- divide by two
x = 7
