<h2>81.48 (81.5 rounded)</h2>

Step-by-step explanation:

from the question 66 is = 81%

Answer:

80

step by step explanation:

when a number is decreased by 19 %, u calculate backwards, making the % to 119% of 66. Hence it becomes 78.54 to be exact, but in the nearest tenth, it becomes 80.

lora16 [44]

The subtraction function

(k-x)(x)

is defined as the subtraction of the two equations, representing each function:

(k-h)(x)=k(x)-h(x)

So, we have

(k-h)(x)=k(x)-h(x)=14x-2-(2x^3+4x-8)=-2x^3+10x+6
