Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. The per

imeter of the rectangle is 2(5x – 2) + 2(3x + 1). If x = 4 centimeters, what is the total distance Zohar needs to cut with the scissors?

Answer:

x  =  80000/L    f

Step-by-step explanation:

When using only three sides for fencing a rectangular area, sides will be

"x "  and   "y "      x = 2*y      x  is the largest side of the rectangular area

                                             we only fence one y side ( the other side is a river

So the perimeter is  L = x  + 2*y      or   L = 4*y

On the other hand if now the area will be 20000 f²

A = x*y = 20000       ⇒    y  =  20000/ x

As the fence material is the same as that of the maximum area

L =  4*y          L = 4* 20000 / x

L*x = 80000

Then   x  =  80000/L

Where L is the quantity of fencing material

Solve the given system by the substitution method <br>5x + y 19 <br>7x-2y = 13​
lesya692 [45]

Answer:

x = 3 , y = 4

Step-by-step explanation:

5x + y = 19 --------- ( 1 )

=> y = 19 - 5x

7x - 2y = 13 ------------ ( 2 )

Substitute y in ( 2 ) :

                        7x - 2( 19 - 5x ) = 13

                        7x - 38 + 10x = 13

                        17x = 13 + 38

                        17x = 51

                           x = 3

Substitute x in ( 1 ) :

                           5x + y = 19

                           5( 3 ) + y = 19

                            15 + y = 19

                              y = 19 - 15

                               y = 4
