Answer:
2 integers: $7 and $8
5-by-step explanation:
compute 3 times square root of 5 and get 6.708. . .
Plot that.
Compute 5 times the square root of 3 and get 8.6602...
Plot that.
See which whole numbers are between those two points. Only two: 7 and 8
Since the question includes $ signs (WHY??) include the $ in your answer.
Answer:
D
Step-by-step explanation:
(4x√5x^2 +2x^2√6)^2
remove the last ^2 by multiplying the parenthesis by each other:
(4x√5x^2 +2x^2√6) * (4x√5x^2 +2x^2√6)
use FOIL & distribute :
4x√5x(4x√5x +2x^2√6) +2x^2√6(4x√5x +2x^2√6)
apply the distributive property once more:
4x^2√5(4x^2√5)+ 4x^2√5(2x^2√6) + (2x^2√6(4x^2√5) +2x^2√6(2x^2√6)
remove parenthesis and combine like terms to get:
104x^4+16x^4√30
answer is D
<h2>
Explanation:</h2><h2 />
In this exercise, we know some facts:
- Lin read for x minutes.
- Elena read for more than that.
The problem tells us nothing about the number of minutes Elena read more than Lin. However, let's say Elena read one-third more than the number of minutes Lin read. Therefore:
<u>For Lin:</u>

<u>For Elena:</u>

the width of Yun's area model is 7x units or ( x-2 )units .
<u>Step-by-step explanation:</u>
Here we have , Yun was trying to factor 7x^2-14x. He found that the greatest common factor of these terms was 7x and made an area model: What is the width of Yun's area model. Let's find out:
We know that area of rectangle :
⇒
.........(1)
Now , According to question we have
⇒ 
⇒ 
Comparing this equation to equation (1) we get that :
⇒
or , 
Therefore , the width of Yun's area model is 7x units or ( x-2 )units .
Answer:
38%
Step-by-step explanation:
Option: 38%.
Total number of numbers: 150
Number of odd numbers: 72
Number of nines: 15
Number of odd numbers other than nine: 72 - 15 = 57
Probability = [number of odd numbers other than nine] / [total number of numbers] = 57/150 = 0.38
0.38 = 38%
