ANSWER

The greatest common factor is
{x}^{2} y

EXPLANATION

We want to find the greatest common factor of

9 {x}^{2} y

and

5 {x}^{4}  {y}^{2}

The prime factorizations are;


9 {x}^{2} y =  {3}^{2}  \times  {x}^{2}  \times y


and


5 {x}^{4}  {y}^{2}  = 5 \times  {x}^{4}  \times  {y}^{2}


The product of the least powers of the common factors is the greatest common factor.


=  {x}^{2} y

A boat takes 2 hours to travel 15 miles upriver against the current. if the rate of the boat in still water is 12 miles per hour
OLga [1]

Answer:

4.5 mph or 9/2 mph

Step-by-step explanation:

Let x be the rate of the current

Formula: Distance = rate x time

where rate upstream =(12-x) and time =2 hours

15=(12-x)(2)

15=24–2x

2x=24–15

2x= 9

x=9/2=4.5 miles per hour (rate of current)

Simplify the expression (4a^2 +2ab) - (2a^2 -ab + b^2) what is the coefficient of the term b^2
iragen [17]

In the simplified expression, the coefficient of the term b² is -1.

<h3>Order to solve Math Operations</h3>

When you solve any Math Operations, it is necessary to be attentive to the order of the operations.

First, you should solve the operation insides of Parentheses. After that priority is given to Exponents. Thereon,  you can solve multiplication or division operations from left to right. Finally, addition or subtraction  from left to right

See the order below

  •       Parentheses
  •       Exponents
  •       Multiplication or Division from left to right
  •       Addition or Subtraction from left to right

The question gives the expression (4a² +2ab) - (2a² -ab + b²). Therefore, for solving the expression you should follow the order of the math operations.

  • Remove the Parentheses

       4a² +2ab -2a² +ab - b²

  • Add similar terms

       2a²+3ab-b²

Like, there are no more similar terms. Therefore, you can represent the expression (4a² +2ab) - (2a² -ab + b²) by  the expression  2a²+3ab-b².
