Richie wants to paint his bedroom ceiling and four walls the ceiling and each of the walls are 8 feet by 8 feet. a gallon of paint covers 40 ft.²write a expression that can be used to find the number of gallons of paint richie needs to buy

is only a line? i think so

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

2 x 503

step-by-step explanation:

its 1006
