Answer:

He set the factored expressions equal to each other. instead of setting them equal to zero

Step-by-step explanation:

f(x) = x^2 + 4x + 3. His work is shown below.

0 = x^2 + 4x + 3

0 = (x + 3)(x + 1)

Here is where we use the zero product property

x+3 = 0 x+1 =0 We do not set them equal to each other

There are four candidates (A. B, C, and D) and 115 voters. When the points were tallied (using 4 points for frst, 3 points for s

aivan3 [116]

Answer:

D had 310 points.

The final ranking is: B,A,D,C

Step-by-step explanation:

The problems states that:

There are 115 votes.

Each ballot has a vote for first place, that counts 4 points, a vote for second place, that counts 3 points, a vote for third place, that counts 2 points and a vote for fourth place that counts 1 point. This means that each ballot has 4+3+2+1 = 10 points.

Since there are 115 voters, there are 115 ballots. This means that the total points of A,B,C and D combined must be equal to 115*10 = 1150. So:

$A + B + C + D = 1150$

We already know that:

A had 320 points, B had 330 points, and C had 190 points.

So:

$A + B + C + D = 1150$

$320 + 330 + 190 + D = 1150$

$D = 310$

B had the most points, followed by A, D and C. So the final ranking is: B,A,D,C
