What does n equal in 6(2n – 3) – 2(6n + 1) = 10n?.

n =

Step-by-step explanation:

6(2n - 3) - 2(6n + 1) = 10n

multiply the brackets

6*2n - 6*3 - 2*6n - 2*1 = 10n

12n - 18 - 12n - 2 = 10n

add or subtract the like terms

0 - 18 = 10n

shift 10 to the right hand side .REmember when u shift multiplication changes to division.

-18 / 10 = n

= n

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

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
