Answer:
Step-by-step explanation:
3 ln(2x) + 7 = 15 Subtract 7 from both sides
3 ln(2x) = 15 - 7 Combine
3 ln(2x) = 8 Divide by 3
ln(2x) = 8/3 Do the division. Take the antilog of both sides.
e^ln(2x) = e^(8/3)
2x = 14.392 Divide by 2
x = 14.392
x = 7. 196
Hey there!
We want to multiply a certain quantity by 2, so we will put the two outside of parentheses and put our variable (x) minus two inside the parentheses to represent this. This will all equal two.
2(x-6)=2
The unknown number is also 7.
I hope that this helps!
Oh don't worry it means length,width and height so you multiply LxWxH
Even integer: 2 x a, where a is a natural number without 0;
Odd integer : 2 x b + 1 , where b is a natural number;
So, 2 x a + 2 x b+ 1 = 2 x ( a + b ) + 1, which is an odd integer.
C. multiplication (the 8 x 9 within the parenthesis)
