If you would like to solve the equation 2 * (x + 4) = 30, you can calculate this using the following steps:

2 * (x + 4) = 30
2 * x + 2 * 4 = 30
2 * x + 8 = 30
2 * x = 30 - 8
2 * x = 22 /2
x = 11

The correct result would be B. 11.

There are 5 green, 1 red, and 1 blue book on the shelf. How many ways can they be arranged if the red and blue book are separate

zloy xaker [14]

Answer:

3,600

Step-by-step explanation:

There are 5 green, 1 red, and 1 blue book on the shelf, 7 books in total.

First, count the number of ways when the red and the blue books are not separated. If these books are not separated, you can count them as one book, so there are 6 books in total which can be arranged in

$6!=1\cdot 2\cdot 3\cdot 4\cdot 5\cdot 6=720$

different ways.

But red and blue books can be rearranged in two ways: blue, red or red, blue, so the number of ways books can be arranged if the red and blue book are not separated is

$2\cdot 720=1,440.$

Hence, the number of ways books can be arranged if the red and blue book are separated is

$7!-1,440=720\cdot 7-1,440=720(7-2)=720\cdot 5=3,600$

Which statements about the graph of the function y=(1/3)

Elena-2011 [213]

Answer: The range of the function is all real numbers is true.

Explanation: the graph of y = 1/3 is just a horizontal line at y = 1/3. so it’s not increasing or decreasing (it’s staying the same). there is no x-intercept, and the y-intercept is (0, 1/3). the range is all the possible y values, and there are infinite possible y values, so it is all real numbers.

hope this helps!
