Prove that (n+5)^2 - (n+3)^2 is a multiple of 4 for all positive integer values of n.

Drupady [299]

Answer:

(n+5)² - (n+3)² =

= (n² + 10n + 25) - (n² + 6n + 9)

= n² + 10n + 25 - n² - 6n - 9

= 4n + 16

= 4(n + 4) ⋮ 4

Which rule describes the x-coordinates in the translation below?.

Ivenika [448]

Answer:

A) x + 0

Step-by-step explanation:

In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)

In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)

Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.

Therefore, the rule for x-coordinates = x + 0

Answer: A) x + 0

Hope this will helpful.

Thank you.

Fill in the blanks:

Murrr4er [49]

Let

x--------> the length side of the rectangle

y--------> the width side of the rectangle

we know that

The perimeter of a rectangle is equal to

$P=2x+2y$

$x=(4a + 96)/(a + 15)$

$y=(4a + 24)/(a + 15)$

Substitute the values of x and y in the formula of perimeter

$P=2*[(4a + 96)/(a + 15)]+2*[(4a + 24)/(a + 15)]$

$P=[(8a + 192)/(a + 15)]+[(8a + 48)/(a + 15)]$

$P=[(16a + 240)/(a + 15)]$

$P=16*[(a + 15)/(a + 15)]$

$P=16\ m$

therefore

<u>the answer part a) is </u>

the total length of fencing material required would be $16\ m$

Part b) Divide the perimeter by the width of the prebuilt fence sections

$\frac{16}{0.50} = 32\ sections$

therefore

<u>the answer Part b) is </u>

$32\ sections$
