Answer:

12,690 people are expected to vote for Mr Salva

Step-by-step explanation:

Here, we want to know the number of people that is expected to vote for a particular candidate in an election given that 54% of people surveyed had said they would vote for the candidate.

Now to calculate the number of people expected to vote for Mr Salva, what we need to do is to find the number out of 23,000 that actually represents a percentage of 54%

To do this, we find 54% of 23,500

mathematically, we have;

54/100 * 23,500

= 12,690

Convert the function into standard form using the distributive property
maw [93]

Answer:

g(x) = \frac{1}{4}x^2 - 3x + 8

Step-by-step explanation:

g(x) = 1/4(x - 4) (x - 8)

g(x) = 1/4(x^2 - 8x - 4x + 32)

g(x) = 1/4(x^2 - 12x + 32)

g(x) = 1/4x^2 - 3x + 8)

2a^2b(5a-3b)

So divide by that you will get

2a^2b(5a-3b)
