Mathematics

Answer:

3

Step-by-step explanation:

All we need to do here is plug in the number 4 for the variable x. Wherever there's an x, kidnap it and replace it with a 4!

\frac{x + 20}{x + 4}

x = 4

\frac{4 + 20}{4 + 4}

Do the addition.

4 + 20 = 24

4 + 4 = 8

\frac{24}{8}

We can simplify this! What is 24 divided by 8?

24/8 = 3

The answer is 3!

the diagonal length of a square window is 40 cm. find the area of the window. Btw any help is appreciated ! :)
7nadin3 [17]
Ok so area is length times width. A square has the same sides all around, which is called a quadrilateral. So you would plug in 40 for length and width. 40x40= 1,600 cm^2 <———— is your answer.

Hope this helped :)

For what value of k will k+9,2k-1 and 2k+7 are the consecutive terms of an A.P
Stolb23 [73]

k = 18

the common difference d of an arithmetic sequence is

d = a₂ - a₁ = a₃ - a₂ = ....

a₂ - a₁ = 2k - 1 - k - 9 = k - 10 and

a₃ - a₂ = 2k + 7 - (2k - 1) = 2k + 7 - 2k + 1 = 8, hence

k - 10 = 8 ⇒ k = 8 + 10 = 18

the 3 consecutive terms are

27, 35, 43
