See below for answers (in bold) and explanations
Step-by-step explanation:
Part A: (h+t)(x) = h(x) + t(x) = (2x-5) + (6x+4) = 2x - 5 + 6x + 4 = 8x - 1
Part B: (h*t)(x) = h(x) * t(x) = (2x-5) * (6x+4) = (2x)(6x) + (2x)(4) + (-5)(6x) + (-5)(4) = 12x² + 8x - 30x - 20 = 12x² - 22x - 20
Part C: h(t(x)) = h(6x + 4) = 2(6x + 4) - 5 = 12x + 8 - 5 = 12x + 3

Hey You!
1 quarter = 25 cents
25 × 6 = 150
1 nickel = 5 cents.
5 × 6 = 30
3 pennies = 3 cents.
3 × 6 = 18
Add them all up:
4.87 + 1.50 + 0.30 + 0.18 = 6.85
There were $6.85 in the coin bank after 6 days.
