If the length of one side of a square is triple and the length of an adjacent side is increased by 10, the resulting rectangle has an area that is 6 times the area of the original square. find the length of a side pf the original square.

10

Step-by-step explanation:

Given: If the length of one side of a square is triple and the length of an adjacent side is increased by .

To Find: If area is times the area of original square find length of a side of original square.

Solution:

Let the side of original square be

area of original square

when length of side is tripled,

new length of one side of square

length of other side is increased by 10 unit

new length of other side of square

new area of resulting rectangle

As area of resulting rectangle is 6 times the original square

as length cannot be zero

Hence the length of a side of original square is

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
