Answer:

3x^2 -2x+1

Step-by-step explanation:

5x^2 -2x+2 -(2x^2 +1)

Distribute the minus sign

5x^2 -2x+2 -2x^2 -1=

3x^2 -2x+1

Remember the large squares are x^2 , the rectangle are x and the small squares are 1

The colored tiles are positive and the white tiles are negative

5x^2 -2x+2 is 5 colored large squares, 2 white rectangles 2 colored small squares

-2x^2 -1 is 2 white large squares and 1 white small square

Add them together

3x^2 -2x+1 3 colored large squares, 2 white squares and 1 colored small square

During the mayoral election,two debates were held between the candidates. The first debate lasted 1 2/3 hours.The second one was

butalik [34]

Answer:

2nd debate was 3 hours long.

Step-by-step explanation:

We have been given that during the mayoral election,two debates were held between the candidates. The first debate lasted 1 2/3 hours. The second one was 1 4/5 times as long as the first one.

Let us find the estimate of time spent on 2nd debate.

1 2/3 hours would be approximately 2 hours. 1 4/5 times would be equal to 2 times.

$2*2=4$

Therefore, the estimated time is less 4 hours.

To find the time spent on 2nd debate, we will multiply 1 2/3 by 1 4/5.

First of all, we will convert mixed fractions into improper fractions as:

$1\frac{2}{3}=\frac{5}{3}$

$1\frac{4}{5}=\frac{9}{5}$

Now, we will multiply both fractions as:

$\frac{5}{3}\times \frac{9}{5}$

$\frac{1}{3}\times \frac{9}{1}$

$\frac{9}{3}\Rightarrow 3$

Therefore, the 2nd debate was 3 hours long.

a companys product development division has 60 employees. Of these, 1/3 are engineers. If 40% of engineers are moved to another

Musya8 [376]

Answer: There will be 12 engineers remaining in the product development department.

Step-by-step explanation:

So the givens are:

60 employees and 1/3 are engineers and if 40% of engineers are moved to another division and how many engineers will remain in the product development department?

So what we need to do:

60 * 1/3 = 60 / 3 = 20

There are 20 engineers.

20 * 40% = 8

There are 8 engineers that are g<u>oing to be moved to another division</u>.

20 - 8 = 12

12 engineers will <u>remain</u> in the development department.

Hence, your answer.
