How would the expression (x^2 + 4)(y^2 + 9) be rewritten using Two Squares? A. (xy+6Y - (2x+3y)
OB. (1-6)2 - (2x+3y)?
C. (xy-6)2 +(3x+2y)?
D. (xy+6) +(3x+2y)?

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

true. i hope this ! go answer some of my newest
