Answer» Answer: Step-by-step EXPLANATION: Using identity (a+b)^3 = a^3 + b^3 + 3AB (a+b) = (-2x)^3 + (1)^3 + 3×(-2x)×1 (-2x + 1) = 6(x + 2) = -8x^3 + 1 - 6x(-2x + 1) = 6x + 12 = -8x^3 + 1 + 12x^2 - 6x = 6x + 12 = -8x^3 + 12x^2 - 6x + 1 is not EQUAL to 6x + 12 This is ur answer.

Between the two towns A and B discussed in Section 7.2.3. Determine if the points (1,5), (2, 3) and (-2,-11) are collinear.Answer is No |
|
Answer» Answer : No as you told I will explain How.. Explanation : it will be collinear if the sum of any two sides are greater than the other. Let A (1,5) , B (2,3) , C (-2,-11) are the POINTS Distance Formula :- √(x1 - x2)2 + ( y1 - y2)2 Distance of AB →√(1-2)2 + (5-3)2 →√(1) + (4) →√5 Distance of BC →√(2-(-2))2 + (3-(-11))2 →√(2+2)2 + (3+11)2 →√(16) + (196) →√212 Distance of AC →√(1-(-2))2 + (5-(-11))2 →√(1+2)2 + (5+11)2 →√(9) + (256) →√265 Therefore, The sum of any two sides will never give the third side Hence, The given points are non - collinear.. Thank-you. |

А - 6а + 8 = 0(а - 4) (а- 2) = 0how the second line derived |
|
Answer» First of all the question should have been "a^2 -6a +8" It has Been Factorised by a method known as factorisation by splitting the middle term. Step-by-step explanation: Step 1: multiply the constant and the coefficient of the term which has a square in it. Step 2: split the middle term as to get 8 in this case. Step 3: in this question the middle term has been splitted into -4 and -2 . so, if u multiply them u will get 8 and if u will add them u will get -6 Step 4: a^2-4a-2a+8. The middle term got splitted and we got this equation. Step 5: Now we can take a common from the 1st two terms and -2 common from the LAST two terms. we get a(a-4)-2(a-4) Step 5: now we will take (a-4) common and we will get (a-4)(a-2).

Prove that 7+ √5 is irrational |
|
Answer» <P>Answer: Mark me as brainliest or i will DELETE the answerLet 7√5 be a RATIONAL number. So, 7√5 = p/q. (p and q are co-prime number and q ≠ 0) => √5 = p/7q As, we can see that p/7q ia rational so √5 should also be rational. But this contradict the fact that √5 is IRRATIONAL. So, by this we can say that 7√5 is irrational number. Hope this helps...:) |

Is 2x-3=2x-7 a linear equation??? Is 2x+1=5 a linear equation??> Plz answer fast I will mark as brainlest!!! |
|
Answer» Answer: Yes 2x + 1 = 5 a linear equation. Because if we solve the equation we get the results as following- 2x + 1 = 5 2x = 5 - 1 2x = 4 x = 4/2 x = 2 Therefore 2x + 1= 5 a linear equation. HOPE it helps. Please mark me as the brainliest. |

calculate the compound interest for second year on rupees 12000 invested for 3 years at 10% per year also find the sum due at the end of 3rd year |
|
Answer» We have to calculate the compound interest for 2nd YEAR on Rs 12,000 invested for 3 years at 10 % per annum. Also find the SUM due at the END of 3rd years. Solution : compound interest for 2nd year = C.I for 2 years - C.I for 1 year = P(1 + r/100)² - P(1 + r/100)¹ = P(1 + r²/10000 + 2r/100 - 1 - r/100) = p(r²/10000 + r/100) = 12,000(100/10000 + 10/100) = 12,000(1/100 + 1/10) = 120 × 11 = 1320 Rs. Sum due at the end of 3rd year = compound interest in 3 years = P(1 + r/100)³ - P = 12000(1 + 10/1000)³ - P = 12000(11/10)³ - 12000 = 12 × 1331 - 12000 = 15972 - 12000 = 3972 Rs. at the end of 3rd year, they should pay 3972 Rs. |
