Answer:
Step-by-step explanation:
Part 1
$6.84 + $4.88 + $8.32 + $4.98 = $25.02
The total cost of the steaks comes to $25.02.
Part 2
2 × 20 = 40
40 - 25.02 = 14.98
1.25 is 5% of 25.02
14.98 - 1.25 = 13.73
The family gets $13.73 back in change.
Part 3
6.84 ÷ 12 = 0.57
4.88 ÷ 8 = 0.61
8.32 ÷ 16 = 0.52
4.98 ÷ 6 = 0.83
Part 4
0.83 - 0.52 = 0.31
They should buy larger steaks to share because the larger steaks are $0.31 cheaper than the smaller steaks.

i think, quick math if you doubt me wait for another answer
Answer: cd(x) = 4x³ — 2x² + 8x — 4
Step-by-step explanation:
c(x) = 4x - 2
d(x) = x² + 2
Therefore, cd(x) = c(x) × d(x)
cd(x) = (4x - 2)(x² + 2)
= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)
= 4x³ + 8x -2x² - 4
cd(x) = 4x³ — 2x² + 8x — 4
Hope this helps?
