Answer:
15*10^15
Step-by-step explanation:
5*10^6= 5*1,000,000
5*1,000,000=5,000,000
3*10^9=3*1,000,000,000=3,000,000,000
5,000,000*3,000,000,000=15,000,000,000,000,000
15*10^15=15,000,000,000,000,000
Hope this helps
x =
Distributive Property:
3 (x - 4) = 12x
3x - 12 = 12x
Combine like terms and isolate the variable:
-12 = 9x
= x
28.1
You can answer questions like this by working backwards.
To do this we can divide 78.2 by 2 and that gets us 39.1
Now we have to subtract 11 from it and that gets us our final answer:
Perimeter = 6x² + 8x
Perimeter = 2(length + width)
perimeter = 2((x²+x)+(2x²+3x))
perimeter = 2(x²+2x² + x+3x)
perimeter = 2(3x² + 4x)
perimeter = 2*3x² + 2*4x
perimeter = 6x² + 8x
