Okay i haven't done this years but base on my knowledge it think that the answer is 6 and that because:
(2x+3) + (3-2x)
(2x+2x+3) +(3-2x+2x)      (what ever you to one side you do the next and that why it cancel each other)
3+3=6
that my explanation hope this help

Write 75% as a decimal and fraction in simplest form.<br> SHOW ALL WORK.
Andrews [41]
75% means 75 per cent, or per hundred.
"Per cent" means "per hundred" or "0.01".
This means that 75% is 0.75 in decimal form.
75% as a fraction means 75 per hundred.
Keep in mind that "per" means to divide.
So, let's translate this into parenthesis.
75 (75) per (/) hundred (100).
Rewrite with only the parenthesis.
75 / 100.
This is 75% in fraction form, but isn't simplified. We can divide both numbers by 25.
75 / 25 = 3
100 / 25 = 4
Your simplified fraction is 3/4.

I hope this helps!

Please help and explain

Answer: Option A

x=\frac{3+i}{2} or x=\frac{3-i}{2}

Step-by-step explanation:

Use the quadratic formula to find the zeros of the function.

For a function of the form

ax ^ 2 + bx + c = 0

The quadratic formula is:

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

In this case the function is:

2x^2-6x+5=0

So

a=2\\b=-6\\c=5

Then using the quadratic formula we have that:

x=\frac{-(-6)\±\sqrt{(-6)^2-4(2)(5)}}{2(2)}

x=\frac{6\±\sqrt{36-40}}{4}

x=\frac{6\±\sqrt{-4}}{4}

Remember that \sqrt{-1}=i

x=\frac{6\±\sqrt{4}*\sqrt{-1}}{4}

x=\frac{6\±\sqrt{4}i}{4}

x=\frac{6\±2i}{4}

x=\frac{3\±i}{2}

x=\frac{3+i}{2} or x=\frac{3-i}{2}
