If m[n+p(2q - 3r)] = 1, which of the variables m, n,p, q or r cannot be 0? a. p b. r c. q d. m e. n

D. m

Step-by-step explanation:

m[n+p(2q - 3r)] = 1

m cannot be zero

Replace [n+p(2q - 3r)]   with some variable, call it x

m*x =1

If we let m = 0

0*x=1

This cannot happen

0 times anything = 0

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the answer is c.
