Answer:
$231.42
Step-by-step explanation:
Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.
The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:
($6.70/ft)(34.54 ft) = $231.42
Bobby should grow an amount greater than 70-61 = 9 inches to become taller than 70 inches. Therefore, the correct answer is that Bobby must grow an amount of x> 9 inches to be taller than 70 inches.
Yikes, looks like you need to work out that last part... ugh.
(x + 1)(x + 1)
(x + 1)²
The last one is correct answer
