What are the zeros of the polynomial y = (3x − 1)(x + 2)(2x + 1)?

2 answers:

5 0

The given polynomial is already factored into functions of degree one. The roots are values that make the three functions equal to zero. 3x-1=0, x=1/3. x+2=0, x=-2. 2x+1=0, x=-1/2. So the three roots are 1/3, -2, and -1/2.

1/3,-2, and -1/2 should be correct

If A completes a particular work in 8 days and B the same work in 24 days. How many days will it take if they work together?

Oliga [24]

A:
1 day = 1/8 of work

B:
1 day = 1/24 of the work

Together:
1 day = A + B = 1/8 + 1/24 = 4/24 = 1/6

1 day = 1/6 of work
1/6 x 6 of work = 1 x 6 days
work = 6 days

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

forsale [732]

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!

Answer:

WX < YW < XY

Step-by-step explanation:

<h2>Angle sum property</h2>

Sum of all angles of triangle = 180

114 + 53 + ∠y = 180

167 + ∠Y = 180

∠Y = 180 - 167

∠Y = 13

The side opposite to smallest angle is shortest.

Angles in ascending order: ∠Y < ∠X < ∠W

Sides in ascending order: WX < YW < XY
