Answer» Answer: (x + 4y)3 ————————— 9 Step-by-step explanation: STEP 1 : x + 4y Simplify —————— 3 Equation at the END of step 1 : ((((x2)+8XY)+(16•(y2)))1) (x+4y) —————————————————————————•—————— 3 3 STEP 2 : Equation at the end of step 2 : ((((x2)+8xy)+(24y2))1) (x+4y) ——————————————————————•—————— 3 3 STEP 3 : x2 + 8xy + 16y2 Simplify ——————————————— 3 Trying to factor a multi variable polynomial : 3.1 Factoring x2 + 8xy + 16y2 Try to factor this multi-variable trinomial using trial and error Found a factorization : (x + 4y)•(x + 4y) DETECTING a perfect square : 3.2 x2 +8xy +16y2 is a perfect square It factors into (x+4y)•(x+4y) which is another way of writing (x+4y)2 How to recognize a perfect square trinomial: • It has three terms • Two of its terms are perfect squares themselves • The remaining term is twice the product of the square ROOTS of the other two terms Equation at the end of step 3 : (x + 4y)2 (x + 4y) ————————— • ———————— 3 3 STEP 4 : Multiplying EXPONENTIAL Expressions: 4.1 Multiply (x+4y)2 by (x+4y) The rule says : To multiply exponential expressions which have the same base, add up their exponents. In our case, the common base is (x+4y) and the exponents are : 2 and 1 , as (x+4y) is the same number as (x+4y)1 The product is therefore, (x+4y)(2+1) = (x+4y)3 Final result : (x + 4y)3 ————————— 9 |

The sum of the first 25 terms of an A.P. is 1700, while its common difference is 6. What is the 31st term of the10.A.P.? |
|
Answer» Answer: Step-by-step explanation: Sₙ = n/2[2A + (n-1)d] 1700 = 25/2[2a + 24d] => 2a + 24d = 1700 * 2/25 => 2a + 24d = 136 => 2a + 24*6 = 136 => 2a = 136 - 144 => 2a = -8 => a = -4. nth TERM of AP is given by tₙ = a + (n-1)d 31st term is t₃₁ = -4 + (31 - 1)6 = - 4 + 180 = 176. |

Find the value of x 7.5% of 80 = x |
|
Answer» Answer: 7.5 percent * 80 = (7.5:100)* 80 = (7.5* 80):100 = 600:100 = 6 Now we have: 7.5 percent of 80 = 6 Question: What is 7.5 percent of 80? Percentage solution with steps: Step 1: Our output VALUE is 80. Step 2: We REPRESENT the unknown value with $x$. Step 3: From step 1 above,$80=100\%$. Step 4: Similarly, $x=7.5\%$. Step 5: This results in a pair of simple equations: $80=100\%(1)$. $x=7.5\%(2)$. Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have $\frac{80}{x}=\frac{100\%}{7.5\%}$ Step 7: Again, the reciprocal of both SIDES gives $\frac{x}{80}=\frac{7.5}{100}$ $\Rightarrow x=6$ Therefore, $7.5\%$ of $80$ is $6$ |

My quUJUUNIS we were in the test?(iv) Places A and B are 100 km apart on a highway. One car starts from A and anotherfrom B at the same time. If the cars travel in the same direction at different speeds,they meet in 5 hours. If they travel towards each other, they meet in 1 hour. Whatare the speeds of the two cars? |
|
Answer» Answer: Let the speed of car at A be x kmph and the speed of car at B be y kmph when the car travel in same direction RELATIVE Speed is x−y Dist=100km t=5 hours ∴ Dist =S×T 100=(x−y)5 x−y=20⟶(I) when car travel in opp direction Relative Speed is x+y Dist=100km t=1 hours Dist=ST 100=(x+y)1 x+y=100⟶(II) Solving (I) & (II) x−y=20 x+y=100
2x=120 x=60km/h y=40km/h Speed of the car at A =60 km/h Speed of the car at B=40 km/h The DIFFERENCE of speeds is 60−40=20 |
