Answer: Length = l
Width = w
2l + 2w = 80cm
l+w = 40cm
l = w+4
w+4 + w = 40cm
2w + 4 = 40cm
2w = 36cm
w = 18cm
l = 22cm

Step-by-step explanation:
Answer:
(0,1)(1,4)
Step-by-step explanation:
Put in any value of x to find y, then you have a coordinate, then plot it
lets say i pick 0 for x
y = 3(0) + 1
y = 1
(0,1)
lets say i also pick 1 for x
y = 3(1)+1
y = 4
You need atleast two points to plot a line, these are two points.
Answer:
a / (a - 4) = a(a + 4) / ((a - 4)(a + 4)) = (a^2 + 4a) / (a^2 - 16) = -(a^2 + 4a) / (16 - a^2)
Answer:
10% probability that the part has at least one flaw
Step-by-step explanation:
We have these following probabilities:
90% probability of the part being flawless.
8% probability of the part having a minor flaw
2% probability of the part having major flaws.
What is the probability that the part has at least one flaw
Minor or major flaws. So 8% + 2% = 10%
10% probability that the part has at least one flaw
