I have posted this same question 3 times now and i've tried working on it but I keep getting stuck. If someone can please help me that would be great thanks! What is the value of k such that (x^3−x2+kx+40)÷(x + 5) has a remainder of zero? Then, factor the polynomial completely.

-5k - 150

i could be wrong

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

(23*2)-12=x     x=34
