Question

Evaluate the expression: –(31 + 2) + 72 – (–5)2.

Answer 1

Answer:

The answer would not be any of the choses about it would be 49.

Step-by-step explanation:

You have to add 31 to 2 and you get 33 then you distribute and put the negative sign on to 33 which makes the equation now -33 + 72 - (-5) 2. Multiply 5 and 2 which is ten which leaves you with -33 + 72 + 10 ( you change it to a addition sign because of distribution). Lastly you add 10 and 72 which is 82 then you add 82 and -33 and you get 49.

Answer 2

Answer:

The correct answer is 49.

Step-by-step explanation:

We are given the following expression and we are supposed to evaluate it:

– (31 + 2) + 72 – (–5) 2

Solving the terms inside the brackets first, following the order of operations to solve a mathematical expression to get:

= - (33) + 72 - (-5) 2

Then we will do the multiplications to get:

= - (33) + 72 - (-10)

Further adding and subtracting the terms:

= 39 - (-10)

= 39 + 10

= 49
