Step-by-step explanation:

First off...1/4 is the same to... .25

1. 12.8 x .25 to 12.80

x .25

multiply 5 with zero which is zero

12.80

x .25

2. multiply 5 with 8 which is 40 ...put 4 above 2

12.80

x .25

3. multiply 5 with 2 which is 10 then add 4, which 14. Leave the four and put 1 on top of 1

12.80

x .25

4 00

4. Then multiply 5 with 1 which is still 5 then add one which is 6

12.80

x .25

64 00

5. then put underneath whatever we have a zero under

12.80

x .25

64 00

6. multiply 2 with 0 which is 0 then 2 with 8 which is 16...put down 6 and put up the number 1 above 2

12.80

x .25

64 00

600

7 . multiply 2 with 2 which is 4 then add 1 which is 5 put down 5 and multiply 2 with 1 soo

Answer from: Quest

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

$\frac{ab}{bc} =\frac{ad}{ab}$

now, we can cross multiply

and we get

$ab\timesab=ad\times bc$

$ab^2=ad\times bc$

so, this could be step to prove it

Seth is using the figure shown below to prove pythagorean theorem using triangle similarity: in the
