The difference of $(8x^2 + 9) - (6x^2 + 2x+2)$ is $=2x^2-2x+7$

Option B is correct.

Step-by-step explanation:

We need to find the difference of $(8x^2 + 9) - (6x^2 + 2x+2)$

Solving:

$(8x^2 + 9) - (6x^2 + 2x+2)$

Multiplying - sign with terms inside the bracket

$=8x^2+9-6x^2-2x-2$

Combining like terms

$=8x^2-6x^2-2x+9-2$

$=2x^2-2x+7$

So, the difference of $(8x^2 + 9) - (6x^2 + 2x+2)$ is $=2x^2-2x+7$

Option B is correct.

Answer:

The price of each hamburger is $3

The price of each hot dogs is $2 .

Step-by-step explanation:

Given as :

The total price of 3 hamburger and 2 hot dogs = $13

The total price of 2 hamburger and 5 hot dogs = $16

Let The price of each hamburger = $x

Let The price of each hot dogs = $y

Now, According to question

3 x + 2 y = 13 .........A

2 x + 5 y = 16 .......B

Now, Solving to eq A and B

3 × (2 x + 5 y ) - 2 × (3 x + 2 y ) = 3 × 16 - 2 × 13

Or, (6 x + 15 y) - (6 x + 4 y) = 48 - 26

Or, (6 x - 6 x) + (15 y - 4 y) = 22

Or, 0 + 11 y = 22

∴ y = $\dfrac{22}{11}$

i.e y = $2

so, The price of each hot dogs = y = $2

Now, Put the value of y into eq B

i.e 2 x + 5 y = 16

or, 2 x + 5 × 2 = 16

or, 2 x = 16 - 10

or, 2 x = 6

∴ x = $\dfrac{6}{2}$

i.e x = $3

So, The price of each hamburger = x = $3

Hence, The price of each hamburger is $3 and The price of each hot dogs is $2 . Answer

Circumference of a circle = 2πr

So,

$circumference = 2\pi \: r \\ = > circumference = 2 \times \frac{22}{7} \times \frac{63 \: cm}{2} \\ = > circumference = 2 \times \frac{11}{7} \times 63 \: cm \\ = > circumference = 2 \times 11 \times 9 \: cm \\ = > circumference = 198 \: cm$
