Answer:
No, it equals 6x-18. The Parentheses are not needed because there is an addition sign because they both are positive. You just add regularly so 2x+4x=6x and -6-12=-18. The result is 6x-18
Answer:
A dilation of 2 about the origin.
Step-by-step explanation:
You can see in the original figure the points are half the points of the transformed figure.
For example the coordinates of H are (0.5,0)
The coordinates of H' are (1,0)
Since 0.5 * 2 = 1
There is a dilation of 2 about the origin.
Answer:
108 cubes
Step-by-step explanation:
A rectangular prism with a volume of 4 cubic units is filled with cubes with side lengths of 1/3 . How many 1/3 unit cubes does it take to fill the prism?
Step 1
We find the volume of the cubes
Side length = 1/3 units
Volume of a cube = Side length ³
Hence,
(1/3 units)³ = 1/27 cubic units
Step 2
A rectangular prism with a volume of 4 cubic units.
The number of 1/3 unit cubes that would fill this rectangular mrism is calculated as:
4 cubic units ÷ 1/27 cubic units
= 4 ÷ 1/27
= 4 × 27/1
= 108 cubes
