Percent change=(change/original) tiimes 100
change= |original-new|
so
12 to 36
|12-36|=|-24|=24
so
pcercent change=100 times (24/12)=100 times 2=200%
50 to 35
|50-35|=|15|=15
percent change=100 times (15/50)=100 times 100 times 0.30=30%
10 to 24
|10-24|=|-14|=14
percent change=100 times (14/10)=100 times 1.4=140%
16 to 44.2
|16-44.2|=|-28.2|=28.2
percent change=100 times (28.2/16)= 100 times 1.7625=176.25%
answers are
-12 inches to 36 inches: 200%
-50 punds to 35 pounds: 30%
-10 gallons to 24 gallons: 140%
-16 centimeters to 44.2 centimeters: 176.25%
We can find a slope by the formula:
y2-y1 = m(x2-x1)
You need to know that points.That's all! Here m is the slope.
Relationship B is represented by B. So C and D are both correct.
We need the diagram pic, otherwise we cant solve your problem.
Answer:
4(3n+2) or 12n+8
Step-by-step explanation:
Given expression is:
The numerator of the fraction will be multiplied with 9n^2- 4
So, Multiplication will give us:
We can simplify the expression before multiplication.
The numerator will be broken down using the formula:
![a^2 - b^2 = (a+b)(a-b)\\So,\\= \frac{8[(3n)^2 - (2)^2]}{6n-4}\\ = \frac{8(3n-2)(3n+2)}{6n-4}](https://tex.z-dn.net/?f=a%5E2%20-%20b%5E2%20%3D%20%28a%2Bb%29%28a-b%29%5C%5CSo%2C%5C%5C%3D%20%5Cfrac%7B8%5B%283n%29%5E2%20-%20%282%29%5E2%5D%7D%7B6n-4%7D%5C%5C%20%3D%20%5Cfrac%7B8%283n-2%29%283n%2B2%29%7D%7B6n-4%7D)
We can take 2 as common factor from denominator
Hence the product is 4(3n+2) or 12n+8 ..
