Factor the polynomial:<br> 462 + 15b - 4
kirza4 [7]

Answer:

15(\frac{458}{15}+b) or

15(b+\frac{458}{15})

Step-by-step explanation:

First we can subtract the 4.

458 + 15b

Now we need to find the GCF, but they do not share any kinds of factors together. This might look ugly, but it is what it is. We factor out 15 to get b by itself.

15(\frac{458}{15}+b) or

15(b+\frac{458}{15})

The number of social media post of Noami has a greater spread when compared to that of Amir.

<h3 /><h3>What is the range and intequartile range of the social media posts?</h3>

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

  • The range of Amir's social media posts = 19 - 15 = 4
  • The range of Noami's social media posts = 10 - 0 = 10

The inter quartile range is the difference between the third quartile and the first quartile of a data set.

IQR = Q3 - Q1

The IQR of Amir's social media posts: 7

The IQR of  Naomi's social media posts = 10

How do you solve this as a solution 9(2 + 3x) &lt; 72
laila [671]

Answer:

x <2

Step-by-step explanation:

9(2 + 3x) < 72

Divide each side by 9

9/9 *(2 + 3x) < 72/9

2+3x < 8

Subtract 2 from each side

2+3x-2 < 8-2

3x<6

Divide each side by 3

3x/3 <6/3

x <2
