Answer:
For length of side = 3 cm
Area of the square = 9 cm²
For length of side = 10.5 cm
Area of the square = 110.25 cm²
For length of side = π cm
Area of the square = 9.869 cm²
Step-by-step explanation:
The area of a square is given as :
Area = Side²
therefore,
For length of side = 3 cm
Area of the square = ( 3 cm )² = ( 3 × 3 ) cm² = 9 cm²
For length of side = 10.5 cm
Area of the square = ( 10.5 cm )² = ( 10.5 × 10.5 ) cm² = 110.25 cm²
For length of side = π cm
Area of the square = ( π cm )²
= ( π × π ) cm²
= 3.14² cm² [π = 3.14]
= 9.869 cm²
Susanne is 16 years old.
b = Bob's age
s = Susanne's age
d = Dakota's age
Bob's age is 4 times greater than Susanne's age:
b = 4s
Dakota is three years younger than Susanne:
d = s - 3
The sum of Bob's, Susanne's, and Dakota's ages is 93:
b + s + d = 93
solve these equations:
b = 4s
d = s - 3
b + s + d = 93
and get:
b = 64 years
s = 16 years
(remember that s = Susanne)
d = 13 years
Answer:
The answer to your question is the third choice 4 / (3d - 12)
Step-by-step explanation:
Data
length = (d -2 ) / (3d - 9)
width = 4/(d - 4)
height = (2d - 6)/(2d - 4)
Process
1.- Multiply the numerators
(d - 2)(4)(2d - 6) = 8(d - 2)(d - 3)
2.- Multiply the denominators
(3d - 9)(d - 4)(2d - 4) = 6(d - 2)(d - 4)(d - 3)
3.- Simplify
8(d - 2)(d - 3) / 6(d - 2)(d - 4)(d - 3)
8 / 6(d - 4)
Simplify 8/3 = 4/3
4/3(d - 4)
