Answer:
(47+37)(47-37)
Step-by-step explanation:
47^2-37^2 is a difference of two squares. a^2-b^2 = (a+b)(a-b) so this expression can be factored to (47+37)(47-37) = (84)(10) = 840

Answer:
2w + 2
Step-by-step explanation:
Width = w
Twice its width  = 2*w =2w
2 inches more than twice its width = 2w + 2
Length = 2w + 2
 
        
             
        
        
        
S = (10 x1 /2) + (1/2x- 2x 1/2²)
5 + (-0.25)
= 4.75
        
             
        
        
        
Let the numbers be x and y.
x*y=HCF*LCM=6*60=360
thus
y=360/x
next we find the list of combinations of x and y and test if they satisfy the conditions above:
(6,60),(12,30),(18,20),(24,15)
out of the above, only (6,60) and (12,30) satisfy both conditions. Thus our answer is:
(6,60) or (12,30)
