Do question 2 please and fill in the blanks

Answer:

We start with the equation:

(x^2 - 1)/(x + 1) = 2

We want to rewrite this in standard form.

We can multiply both sides by (x + 1) to get:

((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)

x^2 - 1 = 2*(x + 1) = 2*x + 2

Now we can move all the terms to one side to get:

x^2 - 1 - 2 - 2*x = 0

x^2 - 2*x - 3 = 0

And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:

[tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1} = \frac{2 \pm 4}{2}[/tex]

Then the two solutions are:

x = (2 + 4)/2 = 3

x = (2 - 4)/2 = -1

Answer:

6*n < - (39 + 3/4)

Step-by-step explanation:

Let's do it in steps:

"Six times a number" can be written as:

6*n

Where n is the "number"

"... is less than negative thirty-nine and three-quarters "

then we have:

6*n < - (39 + 3/4)

This is the inequality we wanted, now we can also solve this for n as:

n < -(39 + 3/4)/6

Given:

The dimensions of a rectangular plot are 50 yards by 41 yards.

To find:

The area of the plot.

Solution:

We know that, the area of a rectangle is

[tex]Area=Length\times width[/tex]

So, the area of the rectangular plot is:

[tex]Area=50\times 41[/tex]

[tex]Area=2050[/tex]

Therefore, the area of the rectangular plot is 2050 square yards.

Step-by-step explanation:

Answer:

7a^4b^2 -9a^2b^2x^2

Step-by-step explanation:

Given (2a²b)² +3(a²b)²-x²(-3ab)²​

Recall that (xy)^a = x^a * y^a

Hence (2a²b)² +3(a²b)²-x²(-3ab)²​

expanding the expression

= (2^2 *a^2+2 *b^2) + 3(a^2+2*b^2) - x^2(-3^2 * a^2b^2)

= 4a^4b^2 + 3a^4b^2 - x^2(9a^2b^2)

simplify

= 7a^4b^2 -9a^2b^2x^2

Answer:

114°

Step-by-step explanation:

here's your solution

=> x° + 66° = 180°

=> x = 180° - 66°

=> x = 114°

hope it helps

Answer:

66°+x=180°[by linear pair]

x=180°- 66°

x=114°.

Answer:

9

Step-by-step explanation:

l l means absolute value

the absolute value of any negative number is the same number but positive

so the absolute value of -9 is positive 9

Answer:

9

Step-by-step explanation:

Absolute value (or the lines) makes everything inside of it positive, so |-9| = 9

Answer:

(1.25, -1.5)

Step-by-step explanation:

The system of equations:

y = -2x + 1

y = -3/2

So we know that the two lines meet at the point where y = -3/2 = -1.5

∴ -1.5 = - 2x + 1

2x = 1 + 1.5 = 2.5

x = 2.5 ÷ 2 = 1.25

So the solution to this system of equation (or where the two lines meet) is the point (1.25, -1.5)

Addition Property of Equality

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.

Answer:

yes he have a great answear

Answer:

6.5%

Step-by-step explanation:

1000 in a box and he orders 5 boxes.

1000x5= 5000

So he orders 5000 paper clips

1 box is £15.40 and he order 5, so £15.40x5= £77

£77 is between £55 and £79.99 so he will get 6.5% discount.

After the discount he will pay  £71.99

Answer: A is equal to 0

Anything’s you time by 0 you get 0 remember that

Step-by-step explanation:

0 and 0.1*0=0 and 0.01*0=0 so 0=0

Step-by-step explanation:

To start, every term has an

x

in common, so we can factor that out. Doing this, we get

x

(

x

2

+

x

−

42

)

=

0

What I have in blue can be factored by a thought experiment. What two numbers have a sum of

1

and a product of

−

42

?

After some trial and error, we arrive at

−

6

and

7

. Thus, this business can be factored as

x

(

x

−

6

)

(

x

+

7

)

=

0

We can leverage the zero product property here, setting all three terms equal to zero. As our zeroes, we get

x

=

0

,

x

=

6

, and

x

=

−

7
