Answer:
-12
Step-by-step explanation:
First, solve in parentheses.
2(-2-4)
=
2(-6)
Next, multiply 2 by -6.
Which equals -12.
So therefore using the distributive property shown above, the answer would be -12.
Length = 3cm
1/2 cm cube = 3 ÷ 1/2 = 3 x 2 = 6
Width = 4cm
1/2 cm cube = 4 ÷ 1/2 = 4 x 2 = 8
Height = 5cm
1/2 cm cube = 5 ÷ 1/2 = 5 x 2 = 10
Number o 1/2 cubes = 6 x 8 x 10 = 480
<u>Question</u>:
A rectangle has a height of 4 and a width of x² + 3x + 2. Express the area of the entire rectangle.
<u>Given:</u>
The height of the rectangle is 4.
The width of the rectangle is 
We need to determine the area of the entire rectangle.
<u>Area of the entire rectangle:</u>
Let us determine the area of the entire rectangle.
The area of the rectangle can be determined using the formula,

Substituting height = 4 and width = 
Thus, we get;

Multiplying the terms by 4, we get;

Thus, the area of the entire rectangle is
