Answer:
Example:
Cube with sides: 3. V= 3x3x3= ?
Cube with sides: 6. V= 6x6x6=?
How many times bigger is the second answer? That’s it!
Step-by-step explanation:
D is answer.
Perimeter is 2x +3x +2x + 3x = 10x where x is unknown factor of distance.
So P = 10x
Velocity is 12 km/hr = .2 km/min
P =1.6 Km = 10x
x= .16 Km 3x = .48 km, 2x=.32 km
Area = .48 X .32 Km^2
= 153600 m^2
Answer:

Step-by-step explanation:
The given equation is :

We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :

We know that, 4×4= 16 and 5×5 = 25
So,

So, the solution of the given equation is 4/5.
The answers are 5 x (80 x 7) and 80 fives plus 7 fives
