Answer:

a=7/2

Step-by-step explanation:

a^2-2a+2a-4-a^2+2a+3a+6=3a+9

You want to solve for "a"

1. Mover all terms on the right side to the left side setting this equation to zero.

2. Combine Like Terms

A rectangular field has an area 28800 sq.meter.its length is twice as long as its width.what is the length of its sides?
AVprozaik [17]
Let 
x---------> the length side of rectangle
y---------> the width side of rectangle

we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2

28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m

the answer is
the length side of rectangle is 240 m
 the width side of rectangle is 120 m
