Can somebody help me out with this please?

Crank

Answer:

2 marbles

Step-by-step explanation:

Lana has 3 bags with x marbles in each bag totaling 12 marbles

3x=12

Divide by 3

3x/3 =12/3

x =4

Each bag has 4 marbles

Markus has 3 bags with y marbles totaling 18 marbles

3y =18

Divide each side by 3

3y/3 =18/3

y =6

Each bag has 6 marbles

6-4 =2

There are 2 more marbles in Markus' bags than in Lara's

X^2 + 32x + 256 = 1 please show steps

Elena L [17]

$\boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}$

<h2>Explanation:</h2>

In this case, we have the following equation:

$x^2+32x+256=1$

But we can write this equation as:

$x^2+32x+256=1 \\ \\ Subtract \ -1 \ from\ both \ sides: \\ \\ x^2+32x+256-1=1-1 \\ \\ x^2+32x+255=0$

So this final result is a quadratic equation written in Standard Form ( $ax^2+bx+c=0$ ). We need to find the solutions to this equations, so let's use quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ a=1 \\ b=32 \\ c=255 \\ \\ \\ x=\frac{-32 \pm \sqrt{(32)^2-4(1)(255)}}{2(1)} \\ \\ x=\frac{-32 \pm \sqrt{1024-1020}}{2} \\ \\ x=\frac{-32 \pm \sqrt{4}}{2} \\ \\ x=\frac{-32 \pm 2}{2} \\ \\ Finally, \ two \ solutions: \\ \\ \boxed{x_{1}=-15} \\ \\ \boxed{x_{2}=-17}$

The sum of three consecutive even numbers is 66. What is the smallest of these numbers?

ahrayia [7]

Your answer would be 22 because it says "sum" which means add. Then it says "of three consecutive even numbers" which means you're going to be adding three of the same even number to get 66. 22 is an even number, so let's try it out: 22 + 22 + 22 = 66. (You can also divide 66 by 3.) 22 is the cOrrect answer.
