Answer:

$2x^2+xy-3y^2$

Step-by-step explanation:

Start by taking everything out of the parentheses:

$3x^2-2xy-2y^2-x^2-(-3xy)-(y^2)$

Note two negatives make a positive:

$3x^2-2xy-2y^2-x^2+3xy-y^2$

Combine like terms:

$3x^2-x^2-2xy+3xy-2y^2-y^2$

Simplify

$2x^2+xy-3y^2$

Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. let x represent the length

Paladinen [302]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the length of each of the equal piece of yarn. Since they are 4 equal pieces of yarn, then the total length of the equal pieces of yarn = 4x.

Also, besides cutting the 4 equal pieces of yarn Julie further cuts a yarn 7.75 inches long, therefore if y represent the total length of all the yarn that she ends up cutting, hence:

y = 4x + 7.75

Since the graph produced by this equation have all points connected to each other, hence this is a continuous graph.
