I did this before and the answer is b
perimeter = 2L +2W
the problem states the length ( L) is 2 meters longer then width, so L = w+2
so perimeter =2(w+2) +2w
24 = 2(w+2) +2w
24 = 2w+4 +2w
24 = 4w+4
20=4w
w=20/4 = 5
Answer:
1:+35
2:-270
3:-12
4+19
5:-15
6:-25
Step-by-step explanation:
Use the quadratic formula .
x^2-2x+11=0
a=1
b=-2
c=11
x=-2+- (-2)^2-4*1*11 divided by 2
x=2+- the square root of -40 divided by 2
There is no real solutions
