find the perimeter of an isosceles triangle with side lengths of 5+x, 5+x, and xy. Write in simplest form.
Zinaida [17]
<h3>Answer: perimeter = 10+2x+xy</h3>

To get the perimeter, you add up all the outer sides

side1+side2+side3 = (5+x)+(5+x)+(xy) = 10+2x+xy

The like terms 5 and 5 add to 10. The other pair of like terms x and x add to 2x. There isn't anything to pair with xy, so we leave it as is.

A line of best fit predicts that when x equals 28 y will equal 27.255 but y actually equals 26 what is the residual in this case
Kobotan [32]

Answer:

The answer is -1.255 for residual value.

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value =  26 - 27.255

Residual values = -1.255
