Just write a equation then plus 10 on each side, then it will be 2x=16 and then find x, so it will be 8 because 2 times 8 equal 16
Answer:
(x+10) and (x-10)
Step-by-step explanation:
The volume of a rectangular box is defined as
Volume = width*height*length
In this case
Volume = 6x^2-600 = 6*(x^2 - 100)
And we also know,
Volume = (6)*height*length
So,
6*(x^2 - 100) = (6)*height*length
This means that
height*length = (x^2 - 100)
height*length = (x+10)*(x-10)
The answer is going to be x=5
Let's write 3:5 = 3k:5k. Then using perimeter formula, we can write that
and k=5 cm. The sides are 15 cm and 25 cm. The area is
