3. if i gallon of paint covers of the wall,
then how much paint is needed for the entire
wall?

need work asap

-- To finish painting the entire wall, you have to paint 1/3 of it 3 times.

-- Each time you paint 1/3 of it, you need 3/4 of a gallon of paint.

-- (3/4 gallon) x (3 times) = 9/4 gallon = 2-1/4 gallons, if you don't spill any.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
