Use the quadratic, x^2+18x=25 to answer the following questions. Part A: Find the value of c that will result in a perfect square trinomial.
x^2+18x+ c=25+c

Part B: Rewrite the above equation into a perfect square binomial form.
〖(x +)〗^2=

Part C: What is the value of x?

50

step-by-step explanation:

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
