Answer:

(x+4)(x+18)

Step-by-step explanation:

Using the factorisation method :

We need 2 numbers that multiply to give +72 and add to give +22 :

To find these numbers we write out all the factors of 72 :

1, 72

2 , 36

3 , 24

4 , 18    ----> These must be the numbers as 4+18 = 22

Now we split +22x into +4x and +18x :

x² + 4x + 18x + 72

Factor the first 2 terms together and the last two terms :

x(x+4) + 18(x+4)

Keep 1 bracket and terms outside the brackets collect them into one:

(x+4)(x+18)

This is our final answer

Answer:

(x+4)(x+18)

Explanation

Let's factor x2+22x+72

x2+22x+72

The middle number is 22 and the last number is 72.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 22

Multiply together to get 72

Can you think of the two numbers?

Try 4 and 18:

4+18 = 22

4*18 = 72

Fill in the blanks in

(x+_)(x+_)

with 4 and 18 to get...

(x+4)(x+18)

Answer:

(x+4)(x+18)

Brooklyn has sold 70% of the 20 candy bars she is supposed to sell for her basketball team. How many candy bars did she sell alr
romanna [79]

Answer:

14 candy Bars

Step-by-step explanation:

Let's under the question before we attempt it.

Total number of Candy Brooklyn is supposed to sell = 20

Percentage of Candy Bars sold= 70%

To know the exact number of Candy sold, it's means we must know the exact value of 70% of 20.

To solve this, we just proceed with mathematical operations.

Therefore:

70% of 20

= 70 / 100 * 20

= 1400 / 100

= 14.

It therefore means that, Brooklyn sold 14 Candy Bars

Two pairs of statements about Jeff's housing expenditures are given below. How can both pairs of statements be true?
Irina18 [472]

Explanation:

Pair 1 is true if Jeff's monthly income is $600/20% = $3,000.

Pair 2 is true if Jeff's monthly income is $1200/10% = $12,000.

Both pairs can be true if Jeff's monthly income increased by a factor of 4 in the 20 years from 1990 to 2010.

Obviously, Jeff spent more on housing in 2010. (Fortunately for Jeff, that larger expenditure was a smaller fraction of his income.)

Tyler believes that an 8-sided die can be used to predict whether customers at his store will use a coupon when making their pur
Alik [6]
"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)

Theoretical Probability of rolling a 1: 1/8 

Experimental Probability of using coupons: 4/48  =  1/12

So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).
