Question

M and n are both integers. Select all the statements that are true if m and n are also equal to each other. m - n = n - m OR +m (- n) = m - n
OR 0 = m - n OR m + n = 0

Answer 1

#1) m - n = n - m

#2) +m (-n) = m - n

#3) 0 = m - n

hope this HELPS!!!!!!!

Answer 2

Answer:

The true statements are;

(i) m - n = n - m

(ii) +m (-n) = m - n

(iii) 0 = m - n

Step-by-step explanation:

We are given that m and n are both integers and we have to select all the statements that are true if m and n are also equal to each other.

(i) The given situation is: m - n = n - m

LHS = m - n

       = m - m   {because m and n are equal}

       = 0

RHS = n - m

       = n - n   {because m and n are equal}

       = 0

Hence, the given statement is true because LHS = RHS = 0.

(ii) The given situation is: +m (- n) = m - n

LHS = +m (- n)

       = m - n

       = m - m  {because m and n are equal}

       = 0

RHS = m - n

       = n - n   {because m and n are equal}

       = 0

Hence, the given statement is true because LHS = RHS = 0.

(iii) The given situation is: 0 = m - n

LHS = 0

RHS = m - n

       = m - m   {because m and n are equal}

       = 0

Hence, the given statement is true because LHS = RHS = 0.

(iv) The given situation is: m + n = 0

RHS = 0

LHS = m + n

       = m + m   {because m and n are equal}

       = 2m

Hence, the given statement is not true because LHS $\neq$ RHS.
