Difference of squares gives which complex factors for the expression x^2+11?

The complex factor for the expression is, .

Step-by-step explanation:

Difference of squares states that it can be factored as follows:

Given the expression:

we can write above as;

=      [ since, i is the imaginary ; ]

By definition of difference of squares:

⇒ .

d≈7.07in

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
