Answer:I don’t speak Spanish .
Step-by-step explanation:
Hi there,
Your question is "twice a number (x) is fifty"
Recall how a number is represented by x.
Twice a number would be represented as 2x.
Therefore, to represent that twice a number is equal to 50, that would result in the expression: 
If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.
Notice how 2 is multiplying the x.
To isolate x, divide that side by 2.
However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.



Equation: 
Solving for x: 25
Hope that helps!
52.5 Yards (yd).
7 + 7 = 14
14 + 14 = 28 ( 10 + 10 + 4 + 4)
14 + 28 = 42 (4 - 2 + 8 = 10 + 20 + 10)
42 + 10.5 = 52.5
⚠⚠ if you need to multiply this by itself (squaring is the proper name) then the answer is 2756.25 Yards.
Answer:
300 %
Step-by-step explanation:
Length of the larger cube =4 cm
So volume 
Length of the smaller cube = 1 cm
Volume of the smaller cube 
So total number of smaller cube 
Surface area of the larger cube 
Surface area of the 64 smaller cube 
So percentage increase in surface area
