A rectangle and a square have the same perimeter if the rectangle is of length 8cm and breadth 6cm, find the length of the square please answer I will mark you as the brainliest |
|
Answer» We know that the perimeter of both the SQUARE and the rectangle are equal. So, first we should find the perimeter of the rectangle. That is, 2(l+b) We know that, l = 8cm & b = 6cm. Substituting here, we get, = 2(8+6) = 2(14) = 28cm Since the perimeter of both of them are equal, we can say that, Perimeter of square = 28cm. But, Perimeter of square = 4 × s. So, 4 × s = 28cm Therefore, s = 28cm/4 S = 7 cm Therefore, the side of the square is 7 cm. Hope it HELPS you! |

Ptove that 21n+4/14n+3 is irreduciblefor every powitive integer n |
|
Answer» Step-by-step explanation: Show that 21n+414n+3,n∈N cannot be reduced? Scan & PAY on Amazon. There are two ways that come to mind. One solution is mine, and the other I’ve taken from the IMO Aops website. For those interested, the problem can be found here: . Euclid’s Algorithm: This one is the one I’m proud of, since I came up with it. YES, I’m sure that everyone ELSE planned on using this one as well, but hey, a solution is a solution. Anyways, let’s get into it. 21n+414n+3 By definition, a quotient is reducible if both the numerator and denominator have a greatest COMMON factor that is greater than 1 . We can use Euclid’s method to determine the GCF between 21n+4 and 14n+3 . If the GCF is shown to be 1 , then we have our proof. So by the Division Theorem: 21n+4=(14n+3)q+r Now, apply Euclid’s Method. 21n+4=(14n+3)⋅1+(7n+1) 14n+3=(7n+1)⋅2+1 7n+1=1(7n+1)+0 So we see that gcf(21n+4,14n+3)=1 , MEANING that the quotient is irreducible this is the answer |

Answer» Answer: Simple or LINEAR EQUATION: An equation is said to be linear is the highest power of the variable concerned in 1. Example: 3x + 13 = 8x – 2 Simultaneous Linear Equation: When there are two or more linear equations containing two or more variables. Example: 3x + 2y = 5, 5x + 3y = 7 Quadratic Equation: When in an equation, the highest power is 2, it is called as the quadratic equation. Example: 2x2 + 7X + 13 = 0 Cubic Equation: As the name suggests, a cubic equation is one which degree 3. Example: 9x3 + 2x2 + 4x -3 = 13 |

if alpha ,beta are the roots of quadratic equation 2x square minus 3x plus 4 equals to 0 then find. 1. 1 divided by alpha square plus 1 divided by beta square |
Answer»
❥ α and β are the roots of the given EQUATION 2x² - 3X + 4 . ● a = 2 ● b = -3 ● c = 4 ☘️ we know that :- → α + β = -b/a→ α + β = -(-3)/2 → α + β = 3/2 .....1) → αβ = c/a→ αβ = 4/2 → αβ = 2 .......2) ▶Now , FINDING Value of 1/α² + 1/β² :-- → 1/α² + 1/β² → (β² + α²)/(αβ)² ......3)
→ a² + b² = (a + b)² - 2ab .....4) ● Now , from 1) , 2) , 3) and 4) → 1/α² + 1/β² = [( α + β)² - 2αβ]/(αβ)² → 1/α² + 1/β² = [(3/2)² - 2 × 2]/2² → 1/α² + 1/β² = [ 9/4 - 4 ]/4 → 1/α² + 1/β² = [ (9 - 16)/4]/4 → 1/α² + 1/β² = -7/4/4 → 1/α² + 1/β² = -7/4 × 1/4 → 1/α² + 1/β² = -7/16 Hence, ༒ Value of 1/α² + 1/β² is -7/16 ━━━━━━━━━━━━━━━━━━━━━━━━━ |

The numerical value of the product of the sides of atriangle is 512 units. Find the minimum possibleperimeter of the triangle (in units). |
|
Answer» Step-by-step EXPLANATION: We KNOW that the SUM of any TWO sides of a triangle is greater than the third side. ....(1) Here the perimeter of the triangle is 14 units. Let divide 14 into 3 parts, so that a+b+c=14, when a,b and c are integers. To COMPLY with (1), the sum of any two of a,b or c should be greater than 2 14
=7. Such possible combinations are (i) 2+6+6 (ii) 3+5+6 (iii) 4+5+5 (iv) 4+6+4 No other combination is possible. So, number of distinct triangles are 4. |
