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

Answer:
the weighted score is 82.03
Step-by-step explanation:
The computation of the weighted score is as follows
= Respective scores × respective test or exam and score
= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79
= 18.9 + 21.6 + 17.04 + 24.49
= 82.03
Hence, the weighted score is 82.03
We simply applied the above formula so that the weighted score could be come
