5 0

Answer:

31x^2-13x

Step-by-step explanation:

to find the perimeter of a triangle, add all sides.

P=a+b+c

P=(5x^2+x)+(8x^2-3x)+(18x^2-11x)

combine like terms

5x^2+8x^2-18x^2= 31x^2

x-3x-11x= -13x

31x^2-13x

<h3>Answer:</h3>

A. y = (-6/5)x +10

<h3>Step-by-step explanation:</h3>

The given line has a negative slope (downward to the right). The only equation offered with a negative slope is the one of selection A.

_____

<em>Complete working</em>

A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...

... slope = (change in y)/(change in x)

The coordinates of two points are given, so we can find the slope as ...

... slope = (-4-2)/(-1-(-6)) = -6/5

There are a number of ways to write the equation of a line, but in slope-intercept form, the slope is the coefficient of x. You will be looking for a choice that has an x-coefficient of -6/5.
