Answer:
The original piece of wood is 108 cm
Step-by-step explanation:
From the given ratio, the shortest is of the ratio 5 and the longest is of the ratio 7
Let the original piece of wood be x
so the sum of the ratios will be;
5 + 6 + 6 + 7 = 24
the shortest length would be 5/24 * x
= 5x/24
the longest will be 7/24 * x = 7x/24
From the question;
7x/24 -5x/24 = 9
(7x-5x) = 24(9)
2x = 24(9)
x = (24 * 9)/2
x = 108 cm

Answer:
6y^3 + 12y^2 - 12y - 4
Step-by-step explanation:
So, you would multiply each in first equation for the second equation, you will got:
= 6y^2 * 6y + 6y^2 * 2 - 2*6y - 2* 2
= 6y^3 + 12y^2 - 12y -4
This would be the final expression
