Four expressions are shown below:

A. 21x + 6
B. 3(7x + 2)
C. 18x + 9
D. 3(6x + 3)

Which two expressions are equivalent to 3(6x + 2 + x)? (5 points)

A. 21x+6

Step-by-step explanation:

3(6x+2+x) = 3(7x+2)

3(7x+2) = 21x+6

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
