Answer:

  18x +9h

Step-by-step explanation:

Such problems are tedious, but not difficult. The trick is to avoid making mistakes in the algebra.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(9(x+h)^2)-(9x^2)}{h}\\\\=\dfrac{9(x^2+2xh+h^2)-9x^2}{h}=\dfrac{18xh+9h^2}{h}=\boxed{18x+9h}

Solve x3 = 1 over 8. <br> 1 over 2 <br> ±1 over 2 <br> 1 over 4 <br> ±1 over 4
cricket20 [7]
X³ =  1/8

Take the cube root of both sides.

∛x³  = ∛(1/8)

Since x³ has 3 of such x multiplying each other so we bring out 1 of the x from the cube root sign as discussed.

x = ∛((1/2)*(1/2)*(1/2))

We bring out 1 of the (1/2) out of the cube root sign as well.

x = 1/2

So the answer is the first option.  1 over 2.

I hope this helps.

when buying lemonade mix , Cece spend $0.72 on a 6- ounce packet and $0.27 on a 3- ounce packet . Use unit rates to determine if
siniylev [52]

6- ounce packet rate = $0.72 .

In order to find the one ounce rate, we need to divide $0.72 by 6.

On dividing 0.72 by 6, we get $0.12.

<em>Therefore, first unit rate is $0.12 per ounce.</em>

3- ounces packet rate = $0.27.

In order to find the one ounce rate, we need to divide  $0.27 by 3.

On dividing 0.27 by 3, we get $0.09.

<em>Therefore, second unit rate is $0.09 per ounce.</em>

<h3>So, we can say that each pair of rates is not equivalent. </h3>
