<span>h(x)=4x2−7x−17
a get like this:
</span>h(x)=f(x)−g(x) =6x2−3x−9-(2x2+4x+8)=6x2−3x−9-2x2-4x-8=4x2−7x−17

Step-by-step explanation:
There could be many answers for this question. In general, the number that comes after 16 is a number with 8 as the sum of its digits.
Explanation:
1st number 31 – Sum of digits is 3 + 1 = 4
2nd number 1031 – Sum of digits is 1 + 0 + 3 + 1 = 5
3rd number 402 – Sum of digits is 4 + 0 + 2 = 6
4th number 16 – Sum of digits is 1 + 6 = 7
Therefore, the missing number could be the single digit number 8 or any of the two-digit numbers 17, 26, 35, 44, 53, 62, 71 or 80. It could also be a bigger number with the digits of any of the given two-digit numbers and 0 for the other digits such as 260 or 7001.

Step-by-step explanation:
If the coat is marked up 28%, then the cost is increased by 28% to produce the selling price.
SP = 45 + 28/100 * 45
SP = Selling Price
SP = 45 + 28*45 / 100
SP = 45 + 1260 / 100
SP = 45 + 12.60
SP = 57.60
