-5 - (-7 - 4x) = -2(3x - 4)       |<em>use distributive property</em>

-5 -(-7) - (-4x) = (-2)(3x) + (-2)(-4)

-5 + 7 + 4x = -6x + 8

2 + 4x = -6x + 8     |<em>-2</em>

4x = -6x + 6      |<em>+6x</em>

10x = 6      |<em>:10</em>

x = 0.6

MissTica

Answer:

1 clean cloth

Step-by-step explanation:

Assuming that the problem is asking the number of clean clothes she picks up when she picked 5 articles.

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the
Olegator [25]

Answer:

Width of the rectangular prism

It is given to us that the volume of the rectangular prism is calculated by the given formula :-

v = lwh

Where,

v = volume

l = length

w = width

h = height

Now,

In the question we are given :-

v = 138.24 cubic inches

h =  9.6 inches

l = 3.2 inches

w = ?

Substitute these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.

Juan put three square tiles with sides 8 centimeters, 10 centimeters, and x centimeters together so that they form a right trian
Elan Coil [88]
Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to x^{2}.
A = x^{2} ---> equation (1)
By using pythagoras rule which states that the x^{2} = hyp^2 - opposite^2---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
x^{2} = 10^{2} - 8^{2} substitute this value in equation (1) then
A = x^{2} = 10^{2} -8^{2}
where A is the area of the square whose side is x
