Solutions 1) Distribute <span> 3×4x+3×3 </span> 2) Simplify 3×4x to 12x <span> 12x+3×3 </span> 3) Simplify 3×3 to 9 <span> 12x+9 Answer = </span>12x+<span>9</span>
You have to take the 3 and multiply what ever is in the parenthasis so 3*4 is 12 but you cant mutliply x so its 12x and them 3*3 is 9 so your answer would be 12x+9

Answer:
THIS MAKES NO SENCE
Step-by-step explanation:
Using the given formula, replace sa with the given surface areas and solve for s:
Surface area = 1200
s = √1200/6
s = √200
s = 14.142
Surface area = 768
s = √768/6
s = √128
s = 11.313
Difference:
14.142 - 11.313 = 2.829 inches
Round answer as needed.
