Answer: 20%

The sum of three consecutive multiples of 7 is 357.find the smallest multiple.
Afina-wow [57]

Answer:

112, 119 and 126.

Step-by-step explanation:

Let the consecutive  multiples of 7 be 7n, 7(n+1) and 7(n+2)  where n is an integer,  then:-

7n + 7n + 7 + 7n + 14 = 357

21n + 21 = 357

21(n + 1) = 357

n = (357/21) - 1

n = 17 + 1 = 16.

So the numbers are 7*16 = 112, 7*17 = 119 and 7*18 = 126.

_______________________________

<h2>Given:-</h2>

<h3>perimeter of rectangle=26cm</h3>

<h3>Area of rectangle=>30cm²</h3>

<h3>{•°• perimeter of rectangle=2(l+b) }</h3>

<h3>{•°•. Area of rectangle=lxb}</h3>

<h3>So, 2(l+b)=26</h3><h3> =>(l+b)=26/2</h3><h3> =>l+b=13</h3><h3> =>l=(13-b) ----------(1)</h3>

<h3>Again,</h3>

<h3> =>lxb=30</h3><h3> =>(13-b)xb=30 {putting the value of l from equation 1}</h3><h3> </h3><h3> =>13b-b²=30</h3><h3> =>b²-13b+30=0</h3><h3> =>b²-10b-3b +30=0</h3><h3> =>b(b-10)-3(b-10)=0</h3><h3> =>(b-10)(b-3)=0</h3><h3> </h3><h3>or,</h3>

<h3> =>b=10 or b=3</h3>

<h3>putting the value of b in equation (1)</h3>

<h3> =>l=(13-b)</h3><h3> =>l=13-10=3 { taking b=10}</h3><h3> =>l=13-3=10 { taking b=3}</h3>

<h3>Hence, length=3 when breadth=10</h3><h3> length=10 when breadth=3</h3>
