Answer:
i think x its 8
Step-by-step explanation:
Polygon EDF and Polygon BAC
They are not similar since their angles are not equal.
You would multiply the two terms which are -6y^2 and -13x^2*y^5.
Multiplying -6 by -13 yields 78, which will be the new coefficient.
Since there is only the x^2 from the second term, that remains the same. However, there are two y values that we can multiply together: y^2 and y^5. y^2 * y^5 = y^(2 + 5) = y^7.
Therefore, your answer is 78x^2*y^7.
Answer: 26 years old
Step-by-step explanation:
- Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
- Simplify the equations --> 4x-12=x+66
- Solve the equation: 3x-12=66 --> 3x=78 --> x=26
This is the same as other age problems, just with the extra step of distributing the multiplication.
A. The mean will increase more than the median.
MEAN
first set: 8,10,12,18,22
8+10+12+18+22 = 70
70/5 =14
second set: 8,10,12,18,22,50
8+10+12+18+22+50= 120
120/6= 20
From 14 to 20
MEDIAN
first set: 8,10,12,18,22
median = 12
second set: 8,10,12,18,22,50
median = 12,18
median = (12+18)/2= 15
from 12 to 15
