Alexander left his house at time zero and drove for 8 minutes to the store at a speed of 1 block every 4 minutes. Then he stopped and went into the store for 7 minutes. From there, he drove in the same direction at a speed of 1 block per minute until he got to the bank, which is 2 blocks away from the store. He stopped at the bank for 2 minutes. Then he drove home at a speed of 2 blocks every minute. Make a graph of showing the number of blocks away from home that Alexander is x x minutes after he leaves his house, until he gets back home.

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

first one because it can't have a fraction in it
