Translate each mathematical phrase into an English phrase.m2 +2n |
|
Answer» -step explanation:The expressions we'll be translating are very straightforward. For example, the phrase "3 more than an UNKNOWN number" becomes the mathematical expression "x + 3." Because the unknown number has no explicitly stated VALUE, we label it with a variable x. To get a value THREE more than x, simply add 3 to it. If this is tricky to you, just think in terms of a real number example. Ask yourself "What is 3 more than the number 7?" Clearly the answer is 10, and you get that answer via the expression "7 + 3 = 10." So, to get 3 more than an unknown number, replace the known number 7 with the unknown number x.Advertisement | Report AdIn this translation problem, the key words were "more than," because they clued you in that addition will be necessary. Each operation has its own cue words, and I've listed them here, with an example for each:Advertisement | Report AdAdditionKelley's CautionsSince subtraction is not commutative, be careful to get the order of the numbers right. Notice that "5 less a number" and "5 less than a number" mean completely different things.More than/greater than: "11 greater than a number" means "x + 11"Sum: "The sum of a number and 6" means "x + 6"SubtractionCritical PointIf no symbol is written between two things, multiplication is implied. Thus, 5y means "5 times y" and 2(x + 1) means "2 times the whole expression (x + 1)." Also, from this point forward, I will usually use the symbol "·" to indicate multiplication, because it's too easy to mix up the other multiplication symbol, —, with the variable x.Fewer than/less than: "7 fewer than a number" means "x - 7"Less: "17 less a number" means "17 - x"Difference: "The difference of a number and 6" means "x - 6"MultiplicationYou've Got ProblemsProblem 1: Translate into a mathematical expression: 5 less than one third of a number.Product: "The product of a number and 3" means "x · 3", also written "3x" (since multiplication is commutative, the order in which you write the numbers doesn't matter)Of: "Half of 20" means " 1�„2 · 20"DivisionQuotient: "The quotient of 10 and a number" means "10 · x"FRACTIONS: Don't forget that any expression written as a fraction is technically a division problem in disguise.Example 1: Translate into mathematical expressions.(a) The sum of 6 and TWICE a numberSolution: The phrase "twice a number" translates into two times the number, or 2x. (Think about it€”twice the number 8 would be 2 · 8 = 16.) The word "sum" indicates that you should add 6 and 2x together to get a final answer of 6 + 2x.(b) The product of 2 and 3 more than a numberSolution: You may be tempted to give an answer of 2 · x + 3, but that equals 2x + 3, or "3 more than 2 times a number." You need to use parentheses to keep the x + 3 together like so: 2(x + 3). Now, the 2 is multiplied by the entire x + 3, not just the x.mark as brainlist plz I will |

Answer» given POLYNOMIAL be p(x)=2x 3 −9x 2 +7x+6. We will now substitute various values of x until we get p(x)=0 as FOLLOWS:Forx=0p(0)=2(0) 3 −9(0) 2 +(7×0)+6=0−0+0+6=6=0∴p(0)=0 Forx=1p(1)=2(1) 3 −9(1) 2 +(7×1)+6=2−9+7+6=15−9=6=0∴p(1)=0Forx=2p(2)=2(2) 3 −9(2) 2 +(7×2)+6=(2×8)−(9×4)+14+6=16−36+14+6=36−36=0∴p(2)=0Thus, (x−2) is a factor of p(x).Now, p(x)=(x−2)⋅g(x).(1)⇒g(x)= (x−2)p(x) THEREFORE, g(x) is obtained by after dividing p(x) by (x−2) as shown in the above image:From the DIVISION, we get the quotient g(x)=2x 2 −5x−3 and now we factorize it as follows: 2x 2 −5x−3=2x 2 −6x+x−3=2x(x−3)+1(x−3)=(x−3)(2x+1)From equation 1, we get p(x)=(x−2)(x−3)(2x+1).Hence, 2x 3 −9x 2 +7x+6=(x−2)(x−3)(2x+1). |

Answer» During the days of the British Indian Empire, the Kingdom of Manipur was one of the princely states. Between 1917 and 1939, some people of Manipur pressed the princely rulers for DEMOCRACY. By later 1930s, the princely state of Manipur negotiated with the British administration its preference to continue to be part of the Indian Empire, rather than part of Burma, which was being separated from India. These negotiations were cut short with the outbreak of World War II in 1939. On 11 August 1947, Maharaja Budhachandra signed an Instrument of Accession, joining India. Later, on 21 September 1949, he signed a MERGER Agreement, merging the kingdom into India, which led to its becoming a Part C State. This merger was later disputed by groups in Manipur, as having been completed without consensus and under duress. The dispute and differing visions for the future has resulted in a 50-year insurgency in the state for independence from India, as well as in repeated episodes of violence among ethnic groups in the state. From 2009 through 2018, the conflict was RESPONSIBLE for the violent deaths of over 1000 peopleStep-by-step explanation: |
