Factor 2a2b3 - 14ab + 16a

zhuklara [117]

Answer:

2a(b^3 - 7b + 8)

Step-by-step explanation:

I'm assuming that 2a2b3 is 2a2b^2. If not, this answer isn't correct.

Look at the whole numbers. Is there a number that divides into them evenly? Yes, 2, so you pull 2 from the problem and divide each number by 2. Do the same for each variable.

2a2b3 - 14ab + 16a

2(ab^3 - 7ab +8a)

2a(b^3 - 7b + 8)

On the checkerboard, 4/10 of the pieces left are red. What fraction of the pieces left are black? Write the equation.

Alexeev081 [22]

Answer:

The fraction of black pieces left is $\frac{6}{10}$

Step-by-step explanation:

Given as :

On the checkerboard , The fraction of red pieces left = $\frac{4}{10}$

Let The fraction of black pieces left = x

So, The fraction of black pieces left = x = 1 - $\frac{4}{10}$

Or, x = $\frac{10-4}{10}$

Or, x = $\frac{6}{10}$

Hence The fraction of black pieces left is $\frac{6}{10}$ Answer
