Answer:

The correct answer is third option

The sum of any number and its opposite is 0

Step-by-step explanation:

It is given an expression,

8.29 * (-5.62 + 5.62)/5.62

<u>To find the correct reason</u>

Here - 5.62 + 5.62 = 0

5.62 is opposite to - 5.62

because sum of a number and its opposite is 0.

Therefore the correct answer is third option.

Answer:

The sum of any number and it's opposite is 0.

Step-by-step explanation:

Given expression is 8.29\cdot\frac{-5.62+5.62}{5.62}

Now we need to find the reason about why the given expression equals to 0.

If you look at the numerator carefully then you will find that numerator contains two terms -5.62 and +5.62 which are exactly same and opposite in sign. So they will cancel each other and give result 0.

After that we get only multiplication and division operation and we know that multiplication by 0 gives 0. that's why the final answer is 0.

So the correct choice is "The sum of any number and it's opposite is 0."

Complete the expressions that would make them a perfect square trinomial.
kirza4 [7]

Answer:

a) 16

b) 100

c) 64

d) \frac{81}{4}[/tex]

Step-by-step explanation:

Perfect square trinomial:

A perfect square trinomial has the following format:

(x \pm a)^2 = x^2 \pm 2ax + a^2

a.

x² – 8x

x^2 - 8x = x^2 - 2ax

So 2a = 8, a = 4. Then

a^2 = 4^2 = 16

The perfect square trinomial is x^2 - 8x + 16

b. x2 + 20x +

2a = 20, so a = 10

a^2 = 10^2 = 100

The perfect square trinomial is x^2 + 20x + 100

C.

x² – 16x +

2a = -16, so a = -8.

a^2 = (-8)^2 = 64

The perfect square trinomial is x^2 - 16x + 64

d. x2 + 9x +

2a = 9, so a = \frac{9}{2}

a^2 = (\frac{9}{2})^2 = \frac{81}{4}

The perfect square trinomial is x^2 + 9x + \frac{81}{4}[/tex]

Lilly has a bag of 140 colored marbles. The bag has an equal number of green and blue marbles and an equal number of red and yel
Anit [1.1K]
Okay. I think to find the number of green and blue marbles each, we have to find the LCM of 8 and 7. The LCM of 8 and 7 is 56. There are 56 green marbles and 56 blue marbles. That a total of 112 marbles combined. 140 - 112 = 28. There are 28 red and yellow marbles. There are an equal number of both. 28/2= 14. There are 14 red marbles in the bag.

If Fred feeds 12 horses for two weeks with 25 bales of hay, how many bales of hay does he need to feed 15 horses for two weeks?​
Dvinal [7]

Answer:

He needs 31.25 bales of hay to feed 15 horses for two weeks

Step-by-step explanation:

This question can be solved using a rule of three.

25 bales of hay feed 12 horses. How many feed 15 horses?

12 horses - 25 bales of hay

15 horses - x bales of hay

12x = 25*15

x = \frac{25*15}{12}

x = 31.25

He needs 31.25 bales of hay to feed 15 horses for two weeks

A function has the function rule y = -7 x - 2. If the input is -4, what is the output? 26 -30 -26 14
GaryK [48]

Answer:

26

Step-by-step explanation:

Since the input is -4, x = -4. The equation then is y = -7(-4) -2

A negative times a negative is a positive, so -7 times -4 is 28.

Now the equation reads y = 28 - 2

Then obviously you just subtract the two and then you get 26.
