X² - 64 = 0
(x - 8)(x + 8) = 0
x = - 8, 8
Your other solution is - 8
(y² - 3)(y⁴ - 6y² + 9)
y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)
y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)
y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27
y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27
y⁶ - 9y⁴ + 27y² - 27
I hope this helps.
Answer:
a) The mode should be measured because the mode finds the number that occurs the most often.
b) The mean should be measured because the mean finds the average number of the data set by adding the all numbers given and dividing the sum by the number of values in the set.
c) The median should be measured because the median finds the middle value of the data set ordered from least to greatest.
a) A circle graph should be used because circle graphs visualize the proportions or percentages of the data.
b) Sorry, but I have no idea.
c) A bar graph should be used because bar graphs compare things between different groups.
