The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4
At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5
-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5
This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!
Factor
b(b+12)=0
set to zero
b=0
b+12=0
b=-12
b=0 or -12
written as this way
b=-12,0
You would need to remove (-2, 1)
Hello
I believe it is 9000000 200000 10000 8000
i could be wrong though
hope this helps
plz mark me as brainliest
The segment I'd 43 units long
