Answer:
-The answer is 
.
Step-by-step explanation:
When you divide numbers/variables with exponents, the exponents will subtract each other:
Answer:
Sam is yeas old, and Dean is (x - 10) year's old, where 'x' is the age of their sister
Step-by-step explanation:
The relationship between the ages of the brothers are;
Sam's age + Dean's age = Their sister's age
Dean's age + 10 = Dean's age + Sam's age
Therefore, we have;
Sam's age = Dean's age + 10 - Dean's age = 10
Sam's age = 10 years
Let 'x' represent their sisters age, we get;
Sam's age + Dean's age = x
10 + Dean's age = x
Dean's age (in variable form) = x - 10
Yes, 24/4 is the fraction for the number six
Prism
Total surface area of the pentagonal prism is 648 square inches
Step-by-step explanation:
In geometry, a pentagon is defined as a five-sided polygon. In a simple pentagon the sum of the internal angles is 540°.
The pentagon base area = 124 square inches
In a pentagonal prism there are two such surfaces (top & bottom)
Hence the area of two pentagons = 124 × 2 = 248 square inches
The lateral area (area of the sides) is made up of 5 equal-sized rectangles
Area of one such rectangle is 80 square inches
Area of five such rectangle is 80 × 5 = 400 square inches
Total surface area of the pentagonal prism = 248 + 400 = 648 square inches
Hence, Total surface area of the pentagonal prism is 648 square inches
