Is 336in bigger or equal to 18 ?

Answer:

The correct option is option D) 2x² + 5x - 3

Step-by-step explanation:

Simplify the expression: (x + 3)(2x - 1)

A) 7x2 - 3

B) 2x2 - 7x - 3

C) 2x2 - 5x - 3

D) 2x2 + 5x - 3

To solve the problem given, we will follow the steps below;

(x + 3)(2x-1)

We will start by opening the parenthesis

x(2x -1) +3(2x-1)

2x² - x + 6x -3

Then we can now add the values with the same coefficient

2x² + 5x -3

Therefore, the correct option is option D) 2x² + 5x - 3

Answer:

55 large boxes and 70 small boxes

Step-by-step explanation:

We understand that there are two unknowns in this problem: the number of large boxes and the number of small boxes.

Let's identify with the letter L the number of large boxes that are transported, and with the letter S the number of small boxes, so we can easily identify the unknowns when writing and reading our equations and final answers.

Set up two equations:

1) one for the total weight of the boxes being transported (which should add up to 4700 pounds), and considering that we have "L" number of large boxes (each one 60 pound weight), and "S" number of boxes (each one 20 pound weight):

60 * L + 20 * S = 4700

2) another equation for the total number of boxes (125) which should be addition of L large boxes and S small ones:

L + S = 125

Now solve for one of the unknowns (let's say for example "S") in the easy second equation we wrote:

S = 125 - L

Now use this expression for "S" (to replace it in terms of L) in the first (more complex) equation:

60 * L + 20 * (125-L) = 4700

Now apply distributive property to remove the parenthesis on the second term on the left of the equation:

60 * L + 2500 - 20 * L = 4700

subtract 2500 from both sides (to group all numerical terms on the right hand side):

60 * L - 20 * L = 4700-2500= 2200

combine the like terms 60L and -20L:

40 * L = 2200

now divide both sides by 40 to solve for L

therefore: L = 2200 / 40 = 55

There are 55 large boxes.

Now to find the number of small boxes, we use this result: "L=55" in the second (simple/easy) equation we created:

S = 125 - L = 70

Therefore, there are 70 small boxes.

The process through which populations of living things adapt and change is known as natural selection.

What is not natural selection examples?

• Natural selection is the term used to describe this process of disparate survival and reproduction. Non-genetic changes that take place throughout an organism's lifetime but cannot be passed on to the next generation, such as gains in muscle mass brought on by nutrition and exercise, are not examples of evolution.
• Natural selection is not influenced by chromosome number. The other three options stand for elements that influence natural selection. Natural selection can take place because of random DNA mutations that produce genetic variation in a population of species.
• Natural selection is a straightforward method that results in long-term population changes in living things. In fact, it is so straightforward that it can be divided into five fundamental steps, which we'll refer to as VISTA in this instance: Variation, Inheritance, Selection, Time, and Adaptation.
