It’s 22 (add 6 after every term)
let x = a number
difference means that its subtraction
twice a number is 2x
so the equation should be
2x-5=3
add 5 to both sides
2x=8
divide both sides by 2
x=4
Answer:
a² + b² = c²
13² + 13² = c²
169 + 169 = c²
338 = c²
c = √338 or 18.385 or 13√2

Answer: 
Step-by-step explanation:
Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by 
Threfore, the area of dry land is the following:
