The correct choice is option a. -3x^2 + xy + 3x - y + 2

Step-by-step explanation:

(xy + 3x + 2) - (3x^2 + y)

= xy + 3x + 2 - (3x^2 + y)

= xy + 3x + 2 - 3x^2 - y

= -3x^2 + xy + 3x - y + 2

The correct answer of the given choices i think it would be A

Answer:

Length :

12

feet

Width :

10

feet

Explanation:

Let the length of the garden be

x

feet.

Therefore, the breadth or width of the garden is

(

x

−

2

)

feet.

So, According to the problem,

x

(

x

−

2

)

=

120

⇒

x

2

−

2

x

=

120

⇒

x

2

−

2

x

−

120

=

0

[Transposing 120 to the L.H.S]

⇒

x

2

+

10

x

−

12

x

−

120

=

0

[Breaking

−

2

x

as

10

x

−

12

x

]

⇒

x

(

x

+

10

)

−

12

(

x

+

10

)

=

0

[Taking the like terms aside]

⇒

(

x

+

10

)

(

x

−

12

)

=

0

[Completing the factorisation]

We know, When two real quantities are multiplied and the product is zero, then one of them or both of them should be zero.

So, Either

x

+

10

=

0

or

x

−

12

=

0

So,

x

=

−

10

or

12

As

x

indicates length,

x

can't be negative.

So,

x

=

12

.

So, The length of the garden is

12

feet and the width of the garden is

(

12

−

2

)

feet =

10

feet.

Answer:

Four possible numbers

-4

-32

-2

-10

Four numbers that are not possible

100

120

20

10

Step-by-step explanation:

I choose the 4 possible numbers because if you add a negative to a negative, the answer will always be a negative. However if you added a positive like 100 to -3, the answer wouldn't be negative so that's why I chose those numbers.

Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
