1. i am a quadrilateral with 4 right angles and opposite sides that are congruent. i can be either a or a 2. i am a quadrilateral that always has 4 congruent sides. i can be either a or a 3. i am a quadrilateral with exactly one pair of parallel sides. i am a 4.i am a quadrilateral with two different sets of opposite sides that are congruent, opposite angles that are congruent and my opposite sides are parallel. i do not have 4 congruent sides. i can be either a or a

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
