Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out expression
12 x 3 x 8 + 3 + 1 - 100 x 2323
Step 2: Multiply
36 x 8 + 3 + 1 - 100 x 2323
Step 3: Multiply
288 + 3 + 1 - 100 x 2323
Step 4: Multiply
288 + 3 + 1 - 232300
Step 5: Add
291 + 1 - 232300
Step 6: Add
292 - 232300
Step 7: Subtract
-232008
Use quadratic formula to solve (shown in picture):
We would get two answers:
x = .3808
and
x = -18.381
The distance from (-2,2) to (5,-3) is 8.6,
(5,-3) to (-4,-1) is 9.2
(-4,-1) to (-2,2) is 3.6
add them all together to get the perimeter
8.6+9.2+3.6= 21.4
so the perimeter is 21.4
