The perimeter of triangle abc is given by the expression 3x2 - 7x + 2.
if ab = 2x - 10x +6 and bc = x-x-4. write an expression in simplest form and standard
form to represent side ac.

Question 1:

For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

We group similar terms:

We take into account that:

Same signs add up and the same sign is placed

Different signs are subtracted and the major sign is placed

Question 2:

For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

We group similar terms:

We take into account that:

Same signs add up and the same sign is placed

Different signs are subtracted and the major sign is placed

Question 3:

For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

We group similar terms:

We take into account that:

Same signs add up and the same sign is placed

Different signs are subtracted and the major sign is placed

Question 4:

For this case we must simplify the following expression:

We eliminate the parentheses taking into account that:

We group similar terms:

We take into account that:

Same signs add up and the same sign is placed

Different signs are subtracted and the major sign is placed

Question 5:

For this case we have that by definition, the perimeter of the triangle will be given by the sum of its sides. That is to say:

We simplify the right side of the equation:

We cleared AC:

were is the equation

the answer

b. they are parallel and will never intersect.
