2/x + 9 is the answer

Answer:

$9 + \frac{2}{x}$

Step-by-step explanation:

I guess this exercise is about translating the problem directions to math language...

The first part states "nine more than...". Usually, "more than" can be translated to addition, in this case the addition of 9 and an expression that needs to be determinated. This can be translated to math language as:

9 + ... (1)

The second part of the statement says "the quotient of two and a number x". Quotient means division, in this case the division of 2 and x. Then we have:

... + $\frac{2}{x}$ (2)

Putting (1) and (2) together, the answer is

$9 + \frac{2}{x}$

How to find the square root of 56 without using a calculator

Olegator [25]

There an old algorythmic method similar to long division:-

7 . 4 8 3
-----------------
) 56. 00 00 00
7 ) 49
  ) ---
   144 ) 7 00
) 576
----
148 8 ) 12400
) 11904
-------
) 496 00
1496 3 ) 44889

THis gives the square root as 7.48 to the nearest hundredth

Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.

Naya [18.7K]

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The given polynomial is

$a) 36x^2-4x+16$

What is the form of perfect square polynomial?

$(ax+b)^2$

we solve this method by using perfect square method

add and subtract 1/9

$36x^2-4x+16+\frac{1}{9}-\frac{1}{9}$

factor 36

$\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )$

Now complete the square

$\frac{143}{9}+36(x^2-\frac{1}{18})^2$

Therefore this is not perfect square trinomial.

Similarly for

$b) 16x^2-8x+36$

Complete square is,

$16(x-\frac{1}{4})^2+35$

This polynomial is also not perfect square trinomial.

$c) 25x^2+9x+4\\$

complete square is,

$25(x+\frac{9}{50})^2+\frac{319}{100}$

This polynomial is not perfect square trinomial.

$d)4x^2+20x+25\\$

complete square is,

$(2x+5)^2$

This polynomial is perfect square trinomial.

Therefore,

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

Jacob drove 8 miles east and then 15 miles north. how far is he from his starting point

Ilya [14]

Answer:

he is 23 miles northeast from this starting spot

Step-by-step explanation:

ok so you start with the directions and notice they are different but this equation worked in our favor because the directions are north and east then all you do is add 8 + 15 and you get 23 so its 23 miles northeast from starting position

I need help lol I’m taking this test

Vera_Pavlovna [14]

Answer:

A) T = -1.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10t+4−2t=2−2(t+4)

10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)

10t+4+−2t=2+−2t+−8

(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)

8t+4=−2t+−6

8t+4=−2t−6

Step 2: Add 2t to both sides.

8t+4+2t=−2t−6+2t

10t+4=−6

Step 3: Subtract 4 from both sides.

10t+4−4=−6−4

10t=−10

Step 4: Divide both sides by 10.

Hope this helps!
