2 answers:

7 0

Try factoring out a 2x from the first 3 terms in the question, like so:

$2x( x^{2} +2x-3)+9$

Now, you can factor the middle quadratic equation and you will have 3 factors plus the constant in the end (the +9). Hope this helps!

PLEASE HELP<br> Identify the first five terms of the sequence in which a, = 3n2 - 1.

Neko [114]

Step-by-step explanation:

you cannot just put the actual numbers in and calculate ?

and you can't provide the correct problem statement, as it seems.

I assume you mean

an = 3n² - 1

a sequence starts with a1, so, n>=1

a1 = 3×1² - 1 = 3-1 = 2

a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11

a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26

a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47

a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74

there, that is all there is to it. you really needed help with that ?

The entry fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5000

Sauron [17]

Answer:

The number of children attended the fair is 1520.

Step-by-step explanation:

We are given the following in the question:

Entry fee foe children = $1.50

Entry fee foe adult = $4.00

Total number of people in fair = 2200

Total money collected = $5000

Let x be the number of children and y be the number of adults in the fair.

Then, we can write the following equations:

$x + y = 2200\\1.5x + 4y = 5000$

Solving the two equations, we have:

$1.5x + 1.5y = 3300\\1.5x + 4y = 5000\\\Rightarrow 2.5y = 1700\\y = 680\\x = 2200-680 = 1520$

Thus, there were 1520 children and 680 adults in the fair.

Plzzzz brainlest I swear

Leona [35]

Answer: 8

Step-by-step explanation: on the left chain, there are 5 4’s, so 4 times 5 is 20 Because you know that, subtract it from 60 to only have the W’s values. So 60-20 is 40 and because there is 5 w’s do 40/5 is 8. Therefore, the value of the w’s is 8 and the value of the 4’s is 20
