On the cube, it measures in numerical order 1 to 6, so:
1,2,3,4,5,6.
We are finding how much red fabric was used for even numbered sides.
So we are looking for sides 2,4,6
Since 20 in. is measured on a side, we can determine the area: 20*2= 40 in.^2 (all sides are same and length*width)
Now we have how much fabric is used on each side, so apply the area to all the even numbers (2,4,6)
40*3= 120 inches
Answer:
3) No solution
4) No solution
Step-by-step explanation:
3) The equation simplifies to ...
5x +15 = 5x +3
15 = 3 . . . . . . . . . . subtract 5x; no value of x will make this true
There is no solution.
__
4) The equation simplifies to ...
4 = -5 . . . . . . . . . subtract y; no value of y will make this true
There is no solution.
Answer:
See below
Step-by-step explanation:
This is a reflection in the x axis ( the 2 ---> -2) and a translation up of 3 units (The +3).
