5. Pierre uses a sheet of printer paper for origami. How can he check if the paper is a rectangle?
A Use a square corner to see if the paper has four right angles.
Fold the paper in half both ways to see if the opposite
sides are congruent.
© Both A and B
Neither A nor B

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
