X is the number
<span>The sum of two numbers is 11, so other number is : 11 - x
</span><span>The sum of their squares is 65
</span>
x^2 + (11 - x)^2 = 65
x^2 + 121 - 2(x)(11) + x^2 = 65
2x^2 - 22x + 121 = 65
2x^2 - 22x + 121 - 65 = 0
2x^2 - 22x + 56 = 0
2(x^2 - 11x + 28) = 0
2(x - 7)(x -4 ) = 0
x - 7 = 0
x = 7
x - 4 =0
x =4
answer: the numbers are 4 and 7
double check:
<span>sum of two numbers is 11:
4 + 7 = 11
</span><span>The sum of their squares is 65
</span><span>4^2 + 17^2 = 16 + 49 = 65

Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery. Washing machines don't have mini Tesla coils inside their machinery!
I hope this helps!
Answer: 100,000 pounds
multiply the mass value by 2000
50×2,000=100,000
I^2 = (sqrt-1)^2 then the square cancels out so the answer is just
-1
Answer:
220
Step-by-step explanation:
110 cannot be the lcm for 20 but 10 and 110
so 220 can be the lcm for 20, 10, and 110
hope this helps
