2[6+4{m-6(7-n-p)+q}]
Algebraic expression​

2(6+4(m−6(7−n−p)+q))

=(2)(6+4(m−6(7−n−p)+q))

=(2)(6)+(2)(4(m−6(7−n−p)+q))

=12+8m+48n+48p+8q−336

Answer =8m+48n+48p+8q−324

❤

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
