Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30

Answer: Mode
<u>Step-by-step explanation:</u>
The given data set is: 10, 10, 12, 13, 15
Mean is the average - find the sum of the data set and divide by the number of terms in the set: 
Mean = 12
Median is the middle term (when the data set is ordered from least to greatest).
Median = 12
Mode is the term that appears the most.
Mode = 10
Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.
225 3x5 is 15 and to the power of 2 is 15x15 so multiply and you get 225 hope it helps
Answer:

Step-by-step explanation:
The slope is always in front of the = sign. The 4 would go into the x axis, and the 1/3 would go in to the y axis
(xy)^8 is simplified by raising a product to a power, and then raising each factor to that power. this means your simplified expression is:
x^8 y^8
