1. Use the distributive property:
Then
2. Separate terms with m in left side and without m in right side:
This expression is false for all values of x, then the equation doesn't have solutions.
Answer: no solution
Answer:
10 miles per 1/4 hour
40 miles per hour
Step-by-step explanation:
Given that:
A car travels 20 miles in 1/2 hour
Miles traveled per hour :
(20 * 2) / 1 = 40 miles per hour
Mile traveled in 1/4 hour :
Distance = speed * time
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
Car traveling 30 miles in 3/4 hours
(30 * 4) /3 = 120 / 3 = 40 miles per hour
Distance = 40 mph * 1/4 = 10 miles per 1/4 hour
(x - 4y)²
(x - 4y)(x - 4y)
x(x - 4y) - 4y(x - 4y)
x(x) - x(4y) - 4y(x) + 4y(4y)
x² - 4xy - 4xy + 16y²
x² - 8xy + 16y²
