<span>The total surface area is SA = 6 </span>×

;
SA = 6 ×

= 6 × 81 = 486

;
Y intercept slope - 5,0
X intercept slope - 0,-4
Place the decimal point right after the first nonzero digit, which is 3.
So you'll go from this

to this

after this move.
Now ask yourself: "how many spots must I move the decimal point to get back to 0.003045?"
The answer is "3 spots to the left"
The exponent of the final answer is -3
The negative indicates "move left" and the 3 tells us how many places to move the decimal
Therefore,
Answer: Choice C)This is assuming you meant to write the -3 as an exponent
The answer is 45x+y=-226. Hope this helps :)
