Answer:

L = 7

Step-by-step explanation:

W = 2L + 1

P = 44

44 = 2(L +W)

44 = 2(L +2L + 1)

44 = 2L +4L + 2

44 = 6L + 2

42 = 6L

L = 7

W = 2(7) + 1

W = 14 + 1

W = 15

1100 = 100%

121 = X

121*100=1100X

12100 = 1100X

X = 12100/1100

X = 11%

What is the value of -97-7 when /= 2? -25 -18 11 45

jok3333 [9.3K]

Step-by-step explanation:

there must be something wrong or missing in your problem description.

what I can read here :

-97 - 7 when divided by 2

-97 - 7 = -104

this divided by 2 is -52.

but there is no such answer.

so, the provided answers and the problem description do not fit to each other.
