Write the equation y=(x-4)(x+2) in standard form

Mathematics

timofeeve [1]3 years ago
6 0

Answer:

y = x² - 2x - 8

Step-by-step explanation:

Given

y = (x - 4)(x + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 2) - 4(x + 2) ← distribute parenthesis

= x² + 2x - 4x - 8 ← collect like terms

= x² - 2x - 8 ← in standard form

A carpenter cut a board 3 3/4 feet long to make a shelf. Before he cut the board, it was 10 1/2 feet long.
viva [34]
Subtract 3 3/4 from 10 1/2.  Note that the LCD is 4, so 10 1/2 = 10 2/4.

What is    10 2/4
               -  3 3/4
-------------------------
                     ?

Since 2/4 is smaller than 3/4, you must borrow 1 from that 10.

Now your problem looks like   9 6/4
                                               -3 3/4
                                             ----------
                                                 6 3/4   (answer)

The remnant of the board is 6 3/4 feet long.

How to do this question plz answer me step by step plzz plz plz plz ​
Step2247 [10]

Answer: 25.6

First, notice that there is 1 adult and 2 children.

A normal adult ticket costs 24. But it's 1/3 off, so 24 * 1/3 = 8 off. That means with the Railcard, it only costs 24 - 8 = 16.

Next, one child ticket costs 12. But it's 60% = 3/5 off, so 12 * 3/5 = 7.2 off. That means with the Railcard, it only costs 12 - 7.2 = 4.8.

Remember there are 2 children, so we multiply by 2 to get 4.8 * 2 = 9.6 for the children.

Final answer: 1 adult + 2 children = 16 + 9.6 = 25.6.

Hope that helped,

Answer:

Okay let me explain this to you so you understand

So what does f(n) mean?

Well F(n) is saying the function, of n.

Basically we need to make n be any random number.

Well what number do we choose?

In your question, it says n is greater than or equal than 2.

lets start with 2

f(n-1)+2

f(2-1)+2

1+2

3

f(2) is 3

lets do this 4 more times

that leaves us with the first 5 terms

these 5 terms are
