Answer:The area method, also sometimes called the box method, is an alternative to the standard algorithmic method (see below) for long multiplication.The standard algorithm is generally a faster method but, unlike the area method, it does not promote understanding or encourage the development of mathematical thinking.please mark as brainliest
Step-by-step explanation:
No, it is not. In a simple random sampling, all produced marbles should have the same probability to be taken off the line. In this case only the first 100 marbles are taken while the rest of the production batch is not randomly sampled
0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
Answer:
1150 sq cm.
Step-by-step explanation:
22*45+20*8= 1150 sq cm.
t=\frac{4\pi n+10+\pi }{20},\:t=-\frac{\pi +4\pi n-30}{8}
