Option A
 is one way to determine the factors of
 is one way to determine the factors of  by grouping
 by grouping
<em><u>Solution:</u></em>
Factoring by grouping means that you will group terms with common factors before factoring
<em><u>Given expression is:</u></em>

Group the first two terms together and then the last two terms together.

We can see that  is common in first two terms
 is common in first two terms
And 3 is common in last two terms
Factor them out


Thus option A is correct
 
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:
side HG is 3
side FG is 5 hypotenuse
sin F = 3/5 = opposite/hypotenuse
cos G is adjacent/hypotenuse
adjacent side is HG which = 3
hypotenuse is 5
 
        
             
        
        
        
X/3 > 7 <== ur equation
multiply both sides by 3
x > 7 * 3
x > 21 <== ur solution
