Answer:
Step-by-step explanation:
width = w
Length = 2w + 4
Area = 240 sq. cm
length * width = 240
(2w + 4) * w = 240
2w *w + 4*w = 240
2w² + 4w = 240
2w² + 4w -240 = 0
2(w²+2w - 120) = 0
2(w² + 12w - 10w - 10*12)=0
2 (w[w + 12] - 10[w + 12] ) = 0
2 (w + 12) (w-10) = 0
Ignore (w + 12) because measurement wont be in negative value
w - 10 = 0
w = 10
Width = 10 cm
length = 2w + 4 = 2*10 + 4 = 20 + 4
Length = 24 cm
It would be a negative integer because it's already postive.
Hi Laila
p+4 -2(p-10)>0
The first thing you need to do is simplify the both sides
So that will be
p-2p + 4+ 20 > 0
-p + 24 > 0
-p > 0-24
-p > -24
Now since we can not have the negative sign in front of P, we need to do something. What we need to do is divide both sides by -1
-p/-1 > -24/-1
p < 24
Remember to change the symbol.
I hope that's help and if you have any further questions please let me know :)
