The answer is 4.
8/x +13 = y --------> y * 2 = 30
divide 2 on both sides so y = 15
8/x + 13 = 15
- 13 - 13
8/x = 2
x =4
Answer:

Answer: Lin is the most consistent and I would want to have them on my team.
Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since
range = max - min
So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.
Answer:
.08cm or 0.08cm
Step-by-step explanation:
First of all, we can see that 20mm is in millimeters, not centimeters.
If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.
There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.
So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.
The formula for the volume of a cuboid is: 
We have the width, length, and volume, so let's plug it in.
To solve for h:
1. Multiply 20 and 100
2. Divide both sides by 2200
3. Divide right side
h = 0.8
Keep in mind that this is in millimeters. In centimeters, it would be .08
9h^2+42h+49
no common factors
trial and error
try first term and last term
all sings are positive since last term and middle terms are possitive
factor leading term and coeficient and try those
9=3*3
49=7*7
(3h+7)(3h+7)
9h^2+21h+21h+49
9h^2+42h+49
true
(3h+7)(3h+7)=(3x+7)^2
answer is (3h+7)^2
