What is the largest digit N for which 2345N is divisible by 6?
kotegsom [21]
Consider this option (this is not the only way):
1. according to the condition 2345N is divisible by <em>6</em>, it means, that N is even number (0;2;4;6 or 8).
2. <em>6</em>=3*2, then the number 2345N is divisible by 3 also. It means, that the number (2+3+4+5+N)=(14+N) is divisible by 3, where N={0|2|4|6|8}.
3. using items 1 and 2:
(14+4)=18; only 18 is divided by 3, it means that N=4.

answer: 4.

Note also, that only 23451; 23454 and 23457 are divided by 3. Only 2345<u>4</u> is divided by 6 (2345<u>4</u>/6=3909).

Let x = hours spent babysitting on Saturday. Choose the equation that
Ne4ueva [31]

The equation that can be used to represent the situation given that x is the number of hours spent babysitting is 4(x + 8) = 56

<h3>How to write and solve equation</h3>

  • Amount paid per hour for babysitting =$4
  • Total amount made = $56
  • Hours spent babysitting on Sunday = 8 hours

Total earned babysitting on Sunday = Hours spent babysitting on Sunday × Amount paid per hour

= 8 × 4

= $32

Number of hours he babysat on Saturday = $56 - (8 × 4) ÷ 4

= 56 - 32 ÷ 4

= 24 ÷ 4

= 6 hours

  • check all that applies

A. 8x+4 = 56

8x = 56 - 4

8x = 52

x = 52/8

x = 6.5

B. 4x+8 = 56

4x = 56 - 8

4x = 48

x = 48/4

x = 12

C. 8(x + 4) = 56

8x + 32 = 56

8x = 56 - 32

8x = 24

x = 24/8

x = 3

D. 4(x + 8) = 56

4x + 32 = 56

4x = 56 - 32

4x = 24

x = 24/4

x = 6

X + x2 - 5x -5 = 0<br> state the possible rational zeros and find all the zeros of the polynomial
Mariulka [41]

Answer:

<em>The zeros of the polynomial are -1 and 5</em>

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

The standard representation of a quadratic equation is:

ax^2+bx+c=0

where a,b, and c are constants.

Solving with the quadratic formula:

\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

We have the following equation to solve:

x+x^2-5x-5=0

Before attempting to solve it, we must simplify the equation.

Collecting like terms and reordering:

x^2-4x-5=0

Here: a=1, b=-4, c=-5

The discriminant of this quadratic equation is:

d=b^2-4ac

d=(-4)^2-4(1)(-5)=16+20=36

Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.

Applying the formula:

\displaystyle x=\frac{4\pm \sqrt{36}}{2(1)}

\displaystyle x=\frac{4\pm 6}{2}

Dividing by 2:

x=2\pm 3

Separating both roots:

x = 2 + 3 = 5

x = 2 - 3 = -1

The zeros of the polynomial are -1 and 5

36 is 75 percent of what
Marta_Voda [28]
36 = 75% of what?

36 = 75% of x

36 = 0.75x

0.75x = 36

x = 36/0.75

x = 48

Therefore 36 is 75 percent of 48

Hope this explains it.

Multiply (x-1)(x³+4x²+4x-1) and combine like terms. Explain how you reached your answer.
Hitman42 [59]

Answer:

x⁴+3x³ -5x +1

Step-by-step explanation:

To multiply this we are going to <u>multiply each term of the binomial by each term of the polynomial.</u>

(x-1)(x^{3}+4x^{2}  +4x-1)\\=x^4+4x^3+4x^2-x -x^3-4x^2-4x+1

Now we are going to <u>combine like terms (this means we are going to sum up terms with the same exponent)</u>

x^4+4x^3+4x^2-x -x^3-4x^2-4x+1 = x^4 +(4x^3-x^3)+(4x^2-4x^2)+(-x-4x)+1\\=x^4+3x^3-5x+1

Thus, the answer is x⁴+3x³ -5x +1
