Understand the problem

(40+70+35−7)×9= (40+70+35-7)\times9=

2

Step-by-step solution

We simplify this expression by observing the order of arithmetic operations which states that exponentiation precedes multiplication, division precedes addition and subtraction, and that parentheses precede everything else.

Therefore, we first start by simplifying the expression within the parentheses. We then multiply the result of the expression within the parentheses by the term that multiplies it:

(40+70+35−7)⋅9=138⋅9=1242 (40+70+35-7)\cdot9= \\ 138\cdot9=\\ 1242 Therefore, the correct answer is option C.
