No matter which natural number "n" that you choose, explain why the following statement can never be true:

maria [59]

First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).

You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.

The bricks are built to form a garden. The perimeter of the outer square is 264 centimeters. The area of the inner square is 900

zhenek [66]

Answer:

Length: 124.7875 cm

Width: 7.2125 cm

Step-by-step explanation:

The perimeter of this area can be calculated as:

P = 2L + 2W

Where P is the perimeter, L is the length and W is the width

If the perimeter is 264 centimeters, we have that:

2L + 2W = 264

L + W = 132

The area can be calculated as:

A = L*W

Where A is the area.

If the area is 900 cm2, we have that:

L*W = 900

From the first equation, we have that L = 132 - W

Using this value in the area equation, we have:

(132-W)*W = 900

132W - W2 = 900

W2 - 132W + 900 = 0

delta = b2 - 4ac = 17424 - 3600 = 13824

sqrt(delta) = 117.575

W1 = (132 + 117.575) / 2 = 124.7875 cm

W2 = (132 - 117.575) / 2 = 7.2125 cm

Using the smaller value for W, the length will be:

L + 7.2125 = 132

L = 124.7875 cm

Which expression is equivalent to the expression below? StartFraction 6 c squared + 3 c Over negative 4 c + 2 EndFraction divide

Triss [41]

Answer:

$\frac{-3c(2c + 1)}{2(2c - 1)}$

Step-by-step explanation:

We want to find the fraction that is equivalent to the fraction below:

Let us put the fraction above in a simpler form:

We can factorise the numerator with 3c and the denominator with -2.

$\frac{3c(2c + 1)}{-2(2c - 1)}\\\\= \frac{-3c(2c + 1)}{2(2c - 1)}$

Therefore, we see that $\frac{-3c(2c + 1)}{2(2c - 1)}$ is equivalent to $\frac{6c^2 + 3c}{-4c +2}$

mylen [45]

Answer:

2x^{2}-3x-5 = 0

use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.

x= 5/2, -1
