Answer :

The value of mSU is 49. Option a is the correct answer.

Let's go through the solution together.

mSU = m + SU

We are given that m = 12 and SU = 7. Substituting these values, we get:

mSU = 12 + 7 = 49

Therefore, mSU = 49.

When we substitute 49 for m, we get mSU = 20 + (49 - 4)2 = 20 + 169 = 189.

When we substitute 77 for m, we get mSU = 20 + (77 - 4)2 = 20 + 193 = 213.

When we substitute 98 for m, we get mSU = 20 + (98 - 4)2 = 20 + 196 = 216.

When we substitute 161 for m, we get mSU = 20 + (161 - 4)2 = 20 + 257 = 277.

Here is a breakdown of the solution:

We are given that m = 12 and SU = 7.

We substitute these values into the equation mSU = m + SU.

This gives us mSU = 12 + 7 = 49.

Option a is the correct answer.
