Apainter uses 1.2 liters of the paint to cover 1m2 of the wall. how many square meters he can cover with 12 liters of paint?

hurry plz i need will mark brainliest!

1o meters square

Step-by-step explanation:

As given that:

1.2 liters cover 1m^2 wall

1 liter will cover 1/1.2 m^2 wall

12 liters will cover (1/1.2)*12 m^2 wall

(1/1.2)*12 m^2 = 10 m^2

So 12 liters of paint will cover 10 meters square wall.

I hope it will help you.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
