Vijay's cuboid shaped room has inner dimensions 12m,8m and 4m, he wants to paint the four walls of his room. The cost of painting is ₹5 per sq m. What is the increment in the cost if roof is also included in area.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

it is true

all the combinations add up i used   calculator

yes   because as the functions are graphed they eventually will intersect unless otherwise
