The value of b is -6.
Explanation:
The expression is
To determine the value of b, we shall solve the expression.
Applying exponent rule, , we get,
Applying exponent rule, , we have,
The expression is of the form, then
Applying this rule, we get,
Dividing both sides by 4, we have,
Hence, the value of b is -6.
Answer:
Step-by-step explanation:
Since the 3 ft edge is on both sides of the pool, each dimension of the pool is 6 ft shorter than the corresponding dimension of the space. The pool will be 15 ft -6 ft = 9 ft in one direction and 20 ft -6 ft = 14 ft in the other direction.
The perimeter of the pool is the sum of its side lengths:
P = 9 ft + 14 ft + 9 ft + 14 ft = 2(9 ft +14 ft) = 2(23 ft)
P = 46 ft
__
The area of the pool is the product of its length and width:
A = (14 ft)(9 ft) = 126 ft²
The perimeter and area are 46 ft and 126 ft², respectively.
