7x=210

x=30

Now,Putting '30' in eq 1 and eq 2

2*30=60

5*30=150

Help me out with this problem please!!and (please tell me how you got the answer.)
Sati [7]
The answers are that the number can equal -4 or 1. 

You can find this by setting the number equal to x.

x^2 (The square of a number) + 3x (three times a number) = 4

x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0

Then you can factor this to find the answers

(x - 4)(x + 1) = 0

Set both equal to 0 and solve.

What is the similarity between numbers; 85,17,19,4 and 2
ICE Princess25 [194]
The correct answer for the question that is being presented above is this one: "<span>They are all divisors of 6460."</span>
<span>
</span>I guess it asks for the Least Common Multiple (LCM) of these numbers.

85= 5*17
17=17
19=19
4=2^(2)
2=2
LCM(85,17,19,4,2)= 5* 17* 19* 2^(2)= 6460.
<span>Conclusion: </span>They are all divisors of 6460.
