Please someone teach me this don't just solve it I wanna learn how to do it thank you!

284 cubic cm

Step-by-step explanation:

Volume = length x width X height

Volume of first shape:  11 x 4 x 6 = 264 cubic cm

Volume of second shape: 5 x 2 x 2 = 20 cubic cm

Vol of 1st + vol of 2nd = 264 + 20 = 284 cubic cm

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
