Answer:
P= 2(3W + 7) + 2(W) = 110.
P= 6W + 14 + 2W = 110.
= 8W + 14 = 110.
= 8W = 110 - 14 = 96
W = 96/8 = 12- inches.
Now solve for (L) by L = 3W + 7 = 3(12) + 7 = 36 + 7 = 43- inches
7=43 inches if this help.can u mark me brainliest

Answer:
There are infinite answers
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−x+5(x+6)=4x+30
−x+(5)(x)+(5)(6)=4x+30(Distribute)
−x+5x+30=4x+30
(−x+5x)+(30)=4x+30(Combine Like Terms)
4x+30=4x+30
4x+30=4x+30
Step 2: Subtract 4x from both sides.
4x+30−4x=4x+30−4x
30=30
Step 3: Subtract 30 from both sides.
30−30=30−30
0=0

Answer:
Correct option: (a) 0.1452
Step-by-step explanation:
The new test designed for detecting TB is being analysed.
Denote the events as follows:
<em>D</em> = a person has the disease
<em>X</em> = the test is positive.
The information provided is:
Compute the probability that a person does not have the disease as follows:
The probability of a person not having the disease is 0.12.
Compute the probability that a randomly selected person is tested negative but does have the disease as follows:
Compute the probability that a randomly selected person is tested negative but does not have the disease as follows:
Compute the probability that a randomly selected person is tested negative as follows:
Thus, the probability of the test indicating that the person does not have the disease is 0.1452.
