Answer:
50.6 cm
Step-by-step explanation:
We can use similar triangles and proportions to solve.  Put the smaller triangle side over the larger triangle side.
x               46.2-14   (This is the length of the short side of the triangle)
--------- = -------------
72.6            46.2
Using cross products
46.2 *x = (46.2-14)  *72.6
46.2 *x = (32.2)  *72.6
46.2 *x = (32.2)  *72.6
46.2x =2337.72
Divide each side by 46.2
46.2/46.2 *x = 2337.72/46.2
x = 50.6
 
        
             
        
        
        
Answer: 8y4+25y3+60y2+10y+7
Step-by-step explanation:
(y2+3y+7)(8y2+y+1)
=(y2+3y+7)(8y2+y+1)
=(y2)(8y2)+(y2)(y)+(y2)(1)+(3y)(8y2)+(3y)(y)+(3y)(1)+(7)(8y2)+(7)(y)+(7)(1)
=8y4+y3+y2+24y3+3y2+3y+56y2+7y+7
=8y4+25y3+60y2+10y+7
hope this helps!:)
