Step-by-step explanation:
These two line segments have a positive slope.
Answer:
3
Step-by-step explanation:
1. Find the area of the green block
Area = L x W x H
1/3 *1*1 = 1/3
2. Find the area of the blue block
1*1*1 =1
3.) Divide the blue area by the green area
1 ÷
= 3
Check : 1/3 + 1/3 + 1/3 = 3/3 3/3 = 1
3 green blocks can fit into 1 blue block
DE+EF=DF
8x+2=x+9
8x-x=9-2
7x=7
x=7/7
x=1
DF=x+9
put the value of x
DF=1+9
DF=10
