5 - (x + 5) - (2x + 4)
5 - x - 5 - 2x - 4
-3x - 4
Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19
7/8 = 0.875.....multiply by 100 to get ur percent = 87.5%
Answer:
The probability of the spinner landing on A is 0.1111.
Step-by-step explanation:
The possible outcomes of a board game is that it can lead on any three of the regions, A, B and C.
The probability of all the outcomes of an event sums up to be 1.

According to the provided information:
P (B) = 3 P (A)
P (C) = 5 P (A)
Compute the probability of the spinner landing on A as follows:

Thus, the probability of the spinner landing on A is 0.1111.
