The factorization of 8x3 – 125 is (2x – 5)(jx2 + kx + 25). what are the values of j and k?

Step-by-step explanation:

we have that

Applying the distributive property to the right side

Combine like terms

Compare with

so

------->

------> substitute the value of j and solve for k

------>

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
