Answer:

See below.

Step-by-step explanation:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

−1.3x−8.9x = -10.2x. This is equivalent to -1.3 + (-8.9X) .

8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .

8.9x−(−1.3x) = 10.2x Neither

−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+1.3x = -7.6x Neither

Take a look yourself

Step-by-step explanation:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .

8.9x−(−1.3x) = 10.2x Neither

−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .

−8.9x+1.3x = -7.6x Neither

The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the heig

marshall27 [118]

Answer:

The length of the rectangle is 9 inches.

The height of the rectangle is 11 inches.

Step-by-step explanation:

Given : The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the height. A box of cereal has a width of 2 inches. It’s height is 2 inches longer than it’s length. If the volume of the box is 198 cubic inches.

To find : What are the length and height of the box ?

Solution :

The width of the box is L inches

The width of the box is W=2 inches

The height is 2 inches longer than it’s length i.e H=L+2

The volume of a rectangular solid is $V=L\times W\times H$
