In order to simplify this expression, we need to add the like terms.

Like terms are terms that have the same variables to the same power.

So we have:

\begin{gathered} 3a^2b+5ab-4ab+ab^2+8a^2b \\ =(3a^2b+8a^2b)+(5ab-4ab)+ab^2 \\ =11a^2b+ab+ab^2 \end{gathered}

Therefore the correct option is the fourth one.

Diano4ka-milaya [45]

The total number of copies that have been sold till date are: 517284

Step-by-step explanation:

Let x be the total number of copies sold

Then

41900 is 801 percent of x

This can be mathematically written as

41900 = 8.1\%\ of\ x\\41900 = 0.081 * x\\x = \frac{41900}{0.081}\\x = 51728.9

Rounding off to nearest whole number

517284

Hence,

The total number of copies that have been sold till date are: 517284

Solve for g.<br><br> 2g = -7g + 9
igor_vitrenko [27]
Solve for g:
2 g = 9 - 7 g
Add 7 g to both sides:
2 g + 7 g = (7 g - 7 g) + 9
7 g - 7 g = 0:
2 g + 7 g = 9
2 g + 7 g = 9 g:
9 g = 9
Divide both sides of 9 g = 9 by 9:
(9 g)/9 = 9/9
9/9 = 1:
g = 9/9
9/9 = 1:
Answer:  g = 1
