To solve this problem, we should use BEDMAS: 1. Brackets 2. Exponents 3. Division/Multiplication 4. Addition/SubtractionLet's simplify the stuff inside the brackets first: Inside the brackets, we have to also follow BEDMAS (do the division, the then addition.) 2/4=0,5-6+0,5=-5,5Now the equation looks like this: 3 (-5,5) — 7^2Now let's do exponents: 7^2=49So now we have: 3 (-5,5) — 49Next, we'll do the multiplication: 3 (-5,5)=-16,5And finally, the subtraction! -16,5 — 49=-65,5Answer: -65,5
