Answer:
x = 0 or 
Step-by-step explanation:
We have the quadratic equation of variable x and we have to solve the equation using the square root property.
Now, we have x(3x - 17) = 0
⇒ 3x² - 17x = 0
⇒ 
⇒ 
⇒ 
Now,square rooting both sides we get,
Therefore, either x = 0 or (Answer)
Answer:
Hmm
Step-by-step explanation:
We can reject the last one: subtracting a non-zero value will result in a smaller value.
So now we have:
<span>2(A + B)
(A + B)2
A2 + B2
If all of them are mulptiplications, then they are all equivalent!
I mean by this, if what you meant is this:
</span>
<span>2*(A + B)
(A + B)*2
A*2 + B*2
If there is no sign, then the multiplication sign is implicit,
and all of these expressions say exactly the same: two of A and two of B.
</span>
It is decreasing, since the y-value is going down.
So there are x girls and x-4 boys and together they make 28:
x+x-4=28
2x-4=28
2x=32
x=16
so there are 16 girls and 12 boys.
the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3
so the best answer is 4:3.
