Answer:
[tex]\Huge \boxed{48}[/tex]
Step-by-step explanation:
[tex]\bigstar\Large\boxed{\textnormal{Order of operations}}\bigstar[/tex]
To use order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) the numbers from left to right. Please Excuse My Dear Aunt Sally!
First, solve parenthesis.
[tex]\displaystyle [26-7(1+2)])[/tex]
[tex]\displaystyle (1+2)=3[/tex]
[tex]\displaystyle 26-7*3[/tex]
[tex]\displaystyle 7*3=21[/tex]
[tex]\displaystyle 26-21=5[/tex]
[tex]\displaystyle 18+6*5[/tex]
Next, multiply numbers from left to right.
[tex]\displaystyle 6*5=30[/tex]
Then, add numbers from left to right.
[tex]\displaystyle 18+30=\boxed{48}[/tex]
[tex]\bigstar\Large\boxed{\textnormal{Therefore, the correct answer is \boxed{48}}}.\bigstar[/tex]
