What is the value of 4|-7| -|9|?

19

Step-by-step explanation:

Okay here , we are dealing with absolute values.

This means we shall be taking the positive values only of terms inside the double tube | |

So -7 absolute value is 7

and thus multiplied by 4 gives 28

and we are subtracting 9 from this;

This gives 28-9 = 19

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
