Plug 3 in for X in the equation.
3(3)^2 + 5(3) +25=
3(9) + 15 +25=
27+15+25=
42+25=
67

So when x=3, the value is 67

I need help with this math
Nana76 [90]

Answer:

2/4 x 7/10 = 14/40, or 7/20.

5/6 x 3/4 = 15/24, or 5/8

3/4 x 2/3 = 6/12, or 1/2

3/10 x 4/5 = 12/50, or 6/25

i think you can finish the rest, all you have to do is multiply the numerator and the numerator, and the denominator and the denominator.

numerator = number on the top

denominator = number on the bottom

then put the two results:

[numerator x numerator]

____________________

[denominator x denominator]

hope this helped! ^^

Use the properties of limits to find the limit.<br> Picture provided below
zhannawk [14.2K]

\dfrac{4x}{x-5}=\dfrac4{1-\frac5x}, and as x\to\infty, the \dfrac5x term vanishes.

\dfrac{4x}{x^2+5}=\dfrac{\frac4x}{1+\frac5{x^2}}, and as x\to\infty, both \dfrac4x and \dfrac5{x^2} vanish.

So

\displaystyle\lim_{x\to\infty}\left(\frac{4x}{x-5}+\frac{4x}{x^2+5}\right)=\lim_{x\to\infty}(4+0)=4

and the answer is C.
