Please help I need to show each step for distributing the -1.

6. Simplify (5x^4 – 3x^2 + 7x – 10) – (2x^4 – 3x^3 + 6x – 17)

(5x^4 + 2x^4) - 3x^2 + (7x - 6x)+ (-10 - 17 ) - 3x^3

3x^4 - 3x^2 + x + 7 - 3x^3

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

its 50 miles away from the starting point
