sweet-ann [11.9K]

Answer with Step-by-step explanation:

Zohar cut a rectangle with a length of 5x – 2

and a width of 3x + 1

We know that:

Perimeter of rectangle is:

Perimeter=2(length+width)

=2(5x-2+3x+1)

=2(8x-1)

=16x-2

Hence, expression which can be used to find the perimeter of the rectangle is:

16x-2

Now, when x=4

16x-2=16×4-2

=62

Hence, when x=4 ,Perimeter=62

Peter has 4 friends. He invited them to his home. He ordered a pizza of his favorite and made it into 5 slices.

Few minutes later, one of his friends Smith came and they enjoyed one slice of pizza each.

Now, the question is what portion of the pizza left for his remaining friends?

Answer :

Peter made the pizza into 5 pieces.

So, $1=\frac{5}{5}$

Peter and Smith had $\frac{1}{5}$ th of the pizza each.

So, the remaining portion = $\frac{5}{5} -(\frac{1}{5}+\frac{1}{5})$

$=\frac{5}{5} -\frac{2}{5}$

$=\frac{3}{5}$
