Hello!

Looking at the graph, we can see that both of the lines intersect at a single point.

Looking at the intersection point, we get an x value of x = 3.

*This can also be proven algebraically by setting the two equations equal to each other:

x + 3 = 4x - 6

3 = 3x - 6

9 = 3x

9/3 = 3x/3

x = 3

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to
