The answer is 2.5 cm

First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12

Answer:

The value of x will be 2.5cm.

Step-by-step explanation:

<h3>Greetings !</h3>

Volume = Length*Width*Height

where,

Volume=120cm³
Length=12cm
Width=x
Height=4cm

$v = l \times w \times h \: ...substitute \: values \\ 120cm {}^{3} = 12cm \times w \times 4cm \\ 120cm {}^{3} = 48cm {}^{2} \times w \: ...divide \: both \: \\ sides \:by \: 48cm {}^{2} \\ \frac{120cm {}^{3} }{48cm {}^{2} } = w \\ w = 2.5cm$

Nadya [2.5K]

Answer:

<em>B: P + 0.25 P</em>

<em>D : 5/4 P</em>

Step-by-step explanation:

The price is P.

The tax is 25% of P, or 0.25P.

The total price is the price plus the tax,

P + 0.25P = P + 1/4P = 4/4P + 1/4P = 5/4P

PLEASE HELP 15 points for brainliest! What is the solution of n^2-49=0

creativ13 [48]

Answer: The correct option are (1). c, (2). d and (3). (b).

Step-by-step explanation: The calculations are as follows:

(1) We are to find the solution of the following quadratic equation:

$n^2-49=0.$

We have

$n^2-49=0\\\\\Rightarrow n^2=49\\\\\Rightarrow n=\pm7~~~~~\textup{[taking square roots on both sides]}$

Thus, the correct option is (c). $\pm7.$

(2) We are to find the solution of the following quadratic equation:

$x^2+64=0.$

We have

$x^2+64=0\\\\\Rightarrow x^2=-64.$

Since there is no real number whose square is negative, so this equation has no solution.

Thus, the correct option is (d). no solution.

(3) We are given to find the side length of a square with an area of 144x².

Let, 'a' denotes the side length of the square.

Then,

$a^2=144x^2\\\\\Rightarrow a=\pm12x.~~~~~~~\textup{[taking square root on both sides]}$

Since the length of the side cannot be negative, so the side length is 12x.

Thus, (b) is the correct option.

The correct option are (1). c, (2). d and (3). (b).
