Step-by-step explanation:
81x⁴ - 16y⁴
(9x²)² - (4y²)²
(9x² + 4y²)(9x² - 4y²)
(9x² + 4y²)(3x + 2y)(3x - 2y)
Answer:
I think 320
Step-by-step explanation:
sorry if wrong but I think it 320
Solve for x by simplifying both sides of the equation, and then isolating the variable.
10. x = -1
12. x = 23/19
Problem work:
y1 =16
y2 = 44.2
( 44.2-16/16) x 100
(1.7625) x 100
So the percent increase (percent change) will be 176.25%
hope this helps
