Step-by-step explanation:
Add 170,000 and 180,000 together then divide by 2. The number is 175000.
The mean of 5 and 15 is 10. (5+15= 20 20/2=10)
Answer:
Sustitute the y-values into the equation.
For y=10,
2(10) + 3 (10 - 5)
20 + 3(5)
20+15
35
For y=57,
2(57) + 3 (57 - 5)
114 + 156
270
For y=35
2(35) + 3 (35 - 5)
70 + 3(30)
70 + 90
160

Step-by-step explanation:
81x⁴ - 16y⁴
(9x²)² - (4y²)²
(9x² + 4y²)(9x² - 4y²)
(9x² + 4y²)(3x + 2y)(3x - 2y)
