Answer» Answer: i hope this is helpful for you Step-by-step explanation: Equation at the end of step 1 (((2 • (X3)) - 7x2) - 7x) + 2 = 0 STEP 2 : Equation at the end of step 2 : ((2X3 - 7x2) - 7x) + 2 = 0 STEP 3 : Checking for a perfect cube 3.1 2x3-7x2-7x+2 is not a perfect cube Trying to factor by pulling out : 3.2 Factoring: 2x3-7x2-7x+2 Thoughtfully split the expression at hand into groups, each group having two terms : Group 1: -7x+2 Group 2: -7x2+2x3 Pull out from each group SEPARATELY : Group 1: (-7x+2) • (1) = (7x-2) • (-1) Group 2: (2x-7) • (x2) Bad news !! Factoring by pulling out fails : The groups have no common factor and can not be added up to form a multiplication. |

Page Sandeep filled water in 4 of an empty tank. After that, Ramakant fille + past more of some tank. Then used 13 post of the tank to water the garden |
|
Answer» The required capacity of the tank left is 340 liters. Step-by-step explanation: Given : Sandeep filled water in 4/7 of an empty tank. After that ,RAMAKANT filled 1/4 part more of the same tank. Then Umesh USED 3/14 part of the tank to water the garden. if the tank has h maximum capacity of 560 liters, To find : How many liter of water will be left in the tank? Solution : LET the capacity of the tank be x. Sandeep filled water in 4/7 of an empty tank i.e. \frac{4}{7}x 7 4
x Ramakant filled 1/4 part more of the same tank i.e. \frac{1}{4}x 4 1
x Umesh used 3/14 part of the tank to water the garden i.e. \frac{3}{14}x 14 3
x The maximum capacity is 560. i.e. x=560 According to question, Water in the tank is =\frac{4}{7}x+\frac{1}{4}x-\frac{3}{14}x= 7 4
x+ 4 1
x− 14 3
x =\frac{32x+14x-12x}{14\times4}= 14×4 32x+14x−12x
=\frac{34X}{14\times4}= 14×4 34x
=\frac{17x}{28}= 28 17x
x=560 =\frac{17\times 560}{28}= 28 17×560
=340=340 Therefore, The required capacity of the tank left is 340 liters. |

Find the Cost Of fencing a rectangular field 62m long and 33m wide at ₹16 Per metre? |
|
Answer» Answer: Given : Length of Field = 62m Breadth of Field = 33m Rate of Fencing = RS 16 per m
To FIND : Total Cost of Fencing Solution : ❏ As we know that, Fencing is done on the BOUNDARY. So, we will find the perimeter of the field then we will find the Total Cost of Fencing by multiplying the Perimeter with Rate of Fencing. ➞ Perimeter of Field = 2 (L + B) ➞ Perimeter of Field = 2 (62 + 33) ➞ Perimeter of Field = 2 × 95 ➞ Perimeter of Field = 190m ________________ Now, ⇒ Cost of Fencing 1m = Rs 16 ⇒ Cost of Fencing 190m = 16 × 190 ⇒ Cost of Fencing 190m = Rs 3,040 Thus Total Cost of Fencing is Rs 3040 hope it helps hope it helpspls mark as brainlliest |
