I will assume the trim costs $3 per sq.ft
area of rectangle=lenght× width
22×23=506sq.ft
if 3 per sq.ft
the how much for 506?
3×506= $1518
5^2(4+6)/2
25(10)/2
250/2
= 125
Step-by-step explanation:
it's late but I hope it helps :)
imagine that the > symbol is just an equal sign
so for example
x+2>4
will look like
x+2=4
and you solve normally
×=2
now we bring the symbol back
x>2
but if you multiple or divide by a negative the sign flips
so say you have
-2x>4
make it into
-2x=4
solve
x=-2
but instead of >
you put
x < -2
