**10 points and brainliest** simplify 8^2+9(12÷3x2)-7 and explain each step

First of all, we must solve the parenthesis. Inside the parenthesis we have a division and a multiplication, which are operation with the same priority. So, we perform them as they appears:

Now we have an exponential, a multiplication and a subtraction. The highest priority is the exponential:

Next the multiplication:

Now we only have sum and subtraction. We can perform these operations in order:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
