No, C is correct. 13 and 2 are prime numbers, 6 is not
There is not enough information here.
For the first equation, you start at 0 and go by 30. The second one you start at 125 then go up gradually by 20 like you did for the first equation. Hope it helped
Hi there! I don't know how you solve these, but at school we solve them like this:
x^2-2x=0
<span>
Δ = b^2-4ac
a = 1; b = - 2; c=0
<span>Δ = 4-0=4
X1,2 = -b+ or - rad </span><span>Δ / 2 a
X1,2 = 2 + or - 2 / 2
X1 = 2 and X2 = 0/2 = 0</span>
So the solutions are 2 and 0
I hope it helped!
