2/5 + 2/4
8/20 = 10/20
8/20 + 10/20 = 18/20
18/20 = 9/10
9/10 = 0.9
Your answer is 9/10 or 0.9

A quadrilateral is a four-sided polygon with four angles.
Answer:
20
Step-by-step explanation:
Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.
