Step-by-step explanation:
x⁴ - 8x² = 0
x⁴ - 8x² + 16 = 0 + 16
x⁴ - 4x² - 4x² + 16 = 16
x²(x²) - x²(4) - 4(x²) + 4(4) = 16
x²(x² - 4) - 4(x² - 4) = 16
(x² - 4)(x² - 4) = 16
(x² - 4)² = 16
The answer is B.
Answer:
Step-by-step explanation:
let the number of bracelet be b
Let the number of necklace be n
If Ashley charges $6 for a bracelet , the total amount charged for b bracelets will be 6b
If she charge $12 for a necklace, the total amount for n necklace will be 12n
If she earned $168 in total, then:
6b + 12n = 168
Divide through by 6
b + 2n = 28
Hence the equation for this situation is b + 2n = 28
Next is to solve for b:
Make b the subject of the formula:
b + 2n = 28
subtract 2n from both sides
b + 2n - 2n = 28 - 2n
b = 28 -2n
Hence the function for b will be b = 28-2n
