Step-by-step explanation:
Answer:
13 units^2
Step-by-step explanation:
one side of the square =
So area of square = Length * Length
= 
*
= 13
First find the slope:
y-y/x-x
5-0/0-(-10
5/+10
slope: 1/2
then use:
y-5. 1
--- = ---
x-0. 2
cross multiply.
2 (y-5)=1 (x-0)
2y-10=x
move the ten to the other side, switch the sign
2y=x+10
divide by 2
y=1/2x+5
final answer is
y=1/2x+5
Total paintings = 6
Number of different places for each painting = 6
Total number of ways she could hang all the painting = 6 × 6 = 36
All the sides of a cube are always the same.
Area = 12 in x 12 in = 144 in^2
Volume = 12 in x 12 in x 12 in = 1728 in^3
Hence, you can confirm all the side of this cube is 12 in.
