Answer:
b+2(b+2b) = 7b so this is incorrect.
3b + b = 4b (correct)
2 * 2b = 4b (correct)
The answer is 3b + b and 2 (2b)
You can use the slope formula to find out how fast object A is moving. It starts off at (0,0) and goes to (2,10). The slope formula is 
. So, you can get the speed by plugging in: 
. Object A is going at 5 meters per second
Answer:
m2 will be 78 because sum of angles in a strt line is 180 hence if m1 is 102 then m2 will be (180-102) i.e.78
Answer:
85 square inches
Step-by-step explanation:
The surface area is the area of all the sides and the bottom
The area of the bottom is
A = s^2 since it is a square
A = 5^2 = 25 in^2
The sides are triangles
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 5)(6)
A = 15 in^2
We have 4 sides
The area of the 4 sides
4*15 = 60 in^2
Add the area of the side to the bottom
25+60 = 85 in^2
