Answer:

Answer: No, they are not equivalent.

Step-by-step explanation:

Since we have given that

Number of own pets = 28

out of 28, there are 16.

So, the ratio would be

Number of own pets = 560

Out of 560, there are 240 are student own pets.

So, the ratio would be

So,

Hence, they are not equivalent.

Answer: 28/16=1.75 560/240=2.33 1.75 doesnt equal 2.33, which means that it is not equivalent. Hope that helps! :)

Rearrange the quadratic equation so that it is equal to 0. Then factor the equation. X^2-4X=-2X+24

The Answers: X²-2X-24 and (X-6)(X+4)

First add the 2x to the other side and subtract 24. This leaves you with X^2 -2x -24 =0 Now you can factor it by finding two numbers that multiply to -24 and add to -2. This is -6 and +4. Now set that as (x-6) and (x+4) you can check this answer by using FOIL.... First outer inner last, by multiplying each of those terms and you should get your original equation. I hope that helps!

The angles of a quadrilateral measures 80 degrees 100 degrees 100 degrees in this order. What kind of quadrilateral has this shape? How do you know?

A parallelogram

Because...

-opposite angles are congruent

-four sides

-angles must equal 360

100 + 100 +80 + y = 360

280 + y = 360

y = 80

-the angle we don't know is 80 degrees

Because...

-opposite angles are congruent

-four sides

-angles must equal 360

100 + 100 +80 + y = 360

280 + y = 360

y = 80

-the angle we don't know is 80 degrees
