Twice of w is 2w and 2 more than 2w is 2w + 2,

So your answer is 2w + 2

Hope this helped!

Prove that the square of an odd number is always 1 more than a multiple of 4

loris [4]

Answer:

By these examples you are able to see that the square of an odd number is always 1 more than a multiple of 4.

Step-by-step explanation:

For examples,

Let's consider squares of 3, 11, 25, 37 and 131.

${3}^{2} = 9$

8 is a multiple of 4, and 9 is more than 8.

${11}^{2} = 121$

120 is a multiple of 4 and 121 is one more than it.

${25}^{2} = 625$

624 is a multiple of 4 and 625 is one more than it.

${37}^{2} = 1369$

1368 is a multiple of 4 and 1369 is one more than 1368.

${131}^{2} = 17161$

17160 is a multiple of 4.

1) 2x – y = 1

aleksandrvk [35]

Answer:

1) (2, 3)

2) (2, -5).

Step-by-step explanation:

2x – y = 1

2x +2y = 10 Subtract to eliminate the 2x:

2x - 2x - y - 2y = 1 - 10

-3y = -9

y = 3.

Plug this into the first equation:

2x - 3 = 1

2x = 4

x = 2.

5x – y =15

x + y = -3 Adding to eliminate y:

5x + x - y + y = 15 + -3

6x = 12

x = 2

Plug this into the first equation:

5(2) - y = 15

-y = 15 - 10 = 5

y = -5.

What is the area of the sector a.) 10π cm^2b.) 16π cm^2c.) 40π cm^2d.) 64π cm^2

Natalija [7]

Answer:

C. 40π cm²

Explanation:

• The central angle of the sector = 225 degrees

• The radius of the sector = 8cm

For a sector of radius r and central angle θ, we calculate the area using the formula below:

$\text{Area}=\frac{\theta}{360\degree}\times\pi r^2$

Substituting the given values, we have:

$\begin{gathered} \text{Area}=\frac{225}{360}\times\pi\times8^2 \\ =\frac{5}{8}\times64\times\pi \\ =5\times8\times\pi \\ =40\pi cm^2 \end{gathered}$

The area of the sector is 40π cm².
