IM NOT UNDERSTAND THIS EQUATION CAN SOMEBODY HELP ME
aleksley [76]

Answer:

  • x = 0, mult: 3
  • x = -4, mult: 2
  • x = -5, mult: 2

Step-by-step explanation:

When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.

  The factor x is zero when x=0.

  The factor (x+4) is zero when x=-4.

  The factor (x+5) is zero when x=-5.

__

The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.

 x = 0 has multiplicity 3.

  x = -4 has multiplicity 2.

  x = -5 has multiplicity 2.

Solve -6x+3-12x-8=31
Gwar [14]
X = -2

Combine terms to get:

-18x - 5 = 31

Add 5 to both sides

-18x = 36

Divide by -18

x = -2

The length of a rectangle exceeds its breadth by 7cm. if the length is decreased by 4cm and the breadth is increased by 3cm, the
riadik2000 [5.3K]

Answer:

16cm

Step-by-step explanation:

Let the breadth = x

The length exceeds = x + 7

The breadth increased = x + 3

Because it said the length decreased by 4 so, the length would be:

x + 7 - 4 = x + 3

Original area:

We learn that:

area = length * breadth

x*(x+7) = (x+3)*(x+3)

x^2 + 7x = (x+3)^2

x^2 + 7x = x^2 + 6x + 9 (We also learn that (a+b)^2 = a^2 + 2ab + b^2

x^2 - x^2 + 7x - 6x = 9

x = 9 (so the breadth = 9)

The length = x + 7 = 9+7 = 16(cm)

Hope this help you :3

Courtney is ordering nachos at a restaurant, and the server tells her that she can have up to three toppings: pico de gallo, oni
aalyn [17]

Answer:

Probability = \frac{1}{9}

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

Probability = P(Onion)\ and\ P(Steak) --- because the events are independent

P(Onion) = \frac{n(Onion)}{Total}

P(Onion) = \frac{1}{3}

P(Steak) = \frac{n(Steak)}{Total}

P(Steak) = \frac{1}{3}

So, we have:

Probability = P(Onion)\ and\ P(Steak)

Probability = P(Onion)\ *\ P(Steak)

Probability = \frac{1}{3} * \frac{1}{3}

Probability = \frac{1}{9}
