Answer:
x=-36
Step-by-step explanation:
Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2
then subtract 9/2x on both sides so itll be
-9/2x -9/2x
because if you do 8/2-9/2 it's -1/2
then multiply the reciprocal to both sides so
which then cancels out -1/2 and makes it
x=-36
Answer:
6.75
Step-by-step explanation:
3/4= 0.75, 6+ 0.75= 6.75
1/4= 0.25, 1/4x3=0.25x3 or 0.25+0.25+0.25= 0.75
Given :
- Area of the trapezium is 140 cm².
