What’s the smallest out of 45, -45, and 90

90 if fractions but -45 anythin else

Step-by-step explanation:

-45

Step-by-step explanation:

- 45 because 45 and 90 is positive and -45 is negative so the - 45 would be smaller

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

2y+y=5

add 2y and y
