–3x6y2

–3x5y6

Multiplying and simplifying the term we get

Option C is correct option.

Step-by-step explanation:

We need to multiply and simplify:

Simplifying the term:

While multiplying, the variables with same bases are multiplied:

In the given question only x^2 and x^4 are variables with same bases, So we get:

So, multiplying and simplifying the term we get

Option C is correct option.

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
