.this is all the question

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
