Step-by-step explanation:
- Multiply 20 by 6 which will give the answer 120 (in inches).
- Then convert 120(inches) to feet by dividing with 12.
- The answer will be 10(feet) needed for six shelves.
20x6= 120
120/12=10
=10 ft

Answer:
<em>B. a = y - k/(x-h)² </em>
Step-by-step explanation:
Given the expression y = a (x-h)² + k
First make a the subject of the formula
Subtract k from both sides
y = a (x-h)² + k
y- k = a (x-h)² + k - k
y - k = a (x-h)²
Divide through by (x-h)²
y - k/(x-h)² = a
a = y - k/(x-h)²
Hence option B is correct
