Answer: 21p^2 + 3qp
Explanation: 
To find the area of the triangle you have to do LxHx1/2
Length = 7p+q
Height = 6p
(7p+q)*6p*1/2 = 21p^2+3qp
I hope this helped!

Answer:
g(L) = 175L - L²
Step-by-step explanation:
350 = 2(length + width)
length + width = 175
Let L be the length, 
L + width = 175
width = 175 - L
Area = length × width 
g(L) = L(175 - L)
g(L) = 175L - L²
 
        
             
        
        
        
Using the normal distribution, it is found that:
a) The pilot is at the 72th percentile.
b) 19.13% of pilots are unable to fly.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean  and standard deviation
 and standard deviation  is given by:
 is given by:

- The z-score measures how many standard deviations the measure is above or below the mean. 
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
 .
.
Item a:
The percentile is the <u>p-value of Z when X = 74.2</u>, hence:


Z = 0.59
Z = 0.59 has a p-value of 0.7224.
72th percentile.
Item b:
The proportion that is able to fly is the <u>p-value of Z when X = 78 subtracted by the p-value of Z when X = 70</u>, hence:
X = 78:


Z = 2
Z = 2 has a p-value of 0.9772.
X = 70:


Z = -0.96
Z = -0.96 has a p-value of 0.1685.
0.9772 - 0.1685 = 0.8087 = 80.87%.
Hence the percentage that is unable to fly is:
100 - 80.87 = 19.13%.

So if she makes 8 and hour and works 40 hours a week
Thats 320 take home every week
Now divide that number by 8 as she is only taking home 1/8th and you are left with only 40 dollars saved a week.
Meaning to get to 457 it would take 11.425 weeks of work
        
             
        
        
        
Answer:
There is an infinite number of lines that pass through the point (2, 11). Therefore, there is an infinite number of equations. To define a single line, you must have at least two points. One point is not enough.
