Answer:

a = 3 , b = -1          or            a = -1 , b = 3

Step-by-step explanation:

x² - 2x - 3 = 0

x² - 3x + 1x - 3 = 0

x ( x - 3 ) +1 ( x - 3 ) = 0

( x - 3 ) ( x + 1 ) = 0

So,

x - 3 = 0                   or                x + 1 = 0

x = 0 + 3                                      x = 0 - 1

x = 3                                            x = -1

Therefore,

( x - a) ( x - b )

As a and b are integers

It can be,

a = 3 , b = -1          or            a = -1 , b = 3

Hope this helps you.

Let me know if you have any other questions :-)

Step-by-step explanation:

Given,

x² - 2x - 3 = 0

x² - (3x - x) - 3 = 0

x² - 3x + x - 3 = 0

x(x - 3) + 1(x - 3) = 0

(x - 3)(x + 1) = 0

x = 3 & -1

Now,

a and b are integers

So

a = 3 & b = -1 or

a = -1 & b = 3

the diagram shows a scale drawing of a playground. The scale of the drawing is 1:500. Work out the perimeter. Give answer in met
IceJOKER [234]

Answer:

The perimeter of the playground is 65 metres

Step-by-step explanation:

Questions like this requires attachment; See attachment for diagram.

From the diagram, we have the following parameters

Length = 2cm

Width = 4.5cm

Required

Calculate the parameter of the actual diagram

First, the actual length and width has to be calculated;

Given that the scale drawing is 1:500

Actual\ Length = 500 * 2cm = 1000cm

Actual\ Width = 500 * 4.5cm = 2250cm

Now, the perimeter can be calculated;

Perimeter\ of\ a\ Rectangle = 2(Length + Width)

Perimeter = 2(1000cm + 2250cm)

Perimeter = 2(3250cm)

Perimeter = 6500cm

However, the question requires answer to be in meters

If 100 cm = 1 m, then

6500cm = \frac{6500m}{100}

6500cm = 65m

Hence, the perimeter of the playground is 65 metres

Please Help me to answerthe questions and options are in picture

Evelyn has initially $524.96, then she paid $32.50, so she will have less than $500. In order to have at least $500, she needs to deposit the value x.

So the initial value, minus the value paid, plus the deposit needs to be greater than or equal 500, so we have the inequality:

524.96-32.5+x\ge500

Solving this inequality for x, we have:

\begin{gathered} 492.46+x\ge500 \\ x\ge500-492.46 \\ x\ge7.54 \end{gathered}

Therefore the correct option is the first one (a).
