I think it's 1.90. I am not fully sure about the answer if it's wrong.
Answer:
7/25 and 0.28 are equal.
Step-by-step explanation:
What you have to do first is the simplest thing: do 7 divided by 25. Don't round anything at all, since the answer will not be repeating. When you find the answer, see if they are both similar
<span>i think you mean discriminant in part A
</span>
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
