Answer:
x = 8
Step-by-step explanation:
4x = 5x - 8 Set both sides equal because they are on a parallelogram
-5x -5x Subtract 5x from both sides
-x = -8 Divide both sides by -1
x = 8
Answer:
A. )3(-3) - 2 = -11
B.) 3(1) - 2 = 1
C.) 3(5) - 2 = 13
Domain: -3, 1, 5
Range: -11, 1, 15
Input: -3, 1, 5
Output: -11, 1, 13
Function: Yes
Linear: Yes
{ (-3, -11) (1, 1) (5, 13) }
Step-by-step explanation:
A.)
- 3x - 2
- 3(-3) - 2 [3 x -3 = -9]
- -9 -2 = -11
B.)
- 3(1) - 2 [3 x 1 = 3 Duh]
- 3 - 2 = 1
C.)
- 3(5) - 2 [3x5 = 15]
2. 15 - 2 = 13
I removed all eight corners, leaving the total area unchanged.
I removed the central cube of the top surface obtaining an increase of the surface area with four units.
I removed one cube from the middle of an edge at the top (any of the four remaining) and I arrived at a figure with ten cubes less then the original one but with the same surface area.
