Answer: yessir it does, 10 times.
Step-by-step explanation:
Well 58 inches is 4 feet, so Amanda has to purchase 2 yards of fabric. So this brings her to $90. If you multiply 90 by 40%, and then subtract that number from 90, you have 54. Multipy 54 by the sales tax and then add that number to 54. So Amanda will have to pay $56.75. Hope this helps, have a nice day :)
C.quadratic. Based on the pattern it is quadratic.
Answer:
Step-by-step explanation:
(-2x⁴ - 4y³ + 4z³ + 6) - (-9x⁴ - 3y³ + 4z³ + 9)
= -2x⁴ - 4y³ + 4z³ + 6 + 9x⁴ + 3y³ - 4z³ - 9
= -2x⁴ + 9x⁴ - 4y³ + 3y³ + 4z³ - 4z³ + 6 - 9
= 7x⁴ - y³ + 0 - 3
= 7x⁴ - y³ - 3
