The answer is 3N is the net force, and the direction is right.
If you add 7, 6, and 4 together, you'll get 17.
If you add 9 and 5 together, you'll get 14.
17 - 14 = 3, so the answer for the net force is 3N.
Since the net force is going in the right direction, the answer is right.
Its closer to 2 because 5 or more is the next bigger number when you are closer to rounding :)
Step-by-step explanation:
5(2x - 3) = 50
expand
10x - 15 = 50
10x = 50 + 15
10x = 65
divide both sides by 10
x = 6.5
Answer:
Step-by-step explanation:
Simplifying
2x + 13 = 0
Reorder the terms:
13 + 2x = 0
Solving
13 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 2x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 2x = 0 + -13
2x = 0 + -13
Combine like terms: 0 + -13 = -13
2x = -13
Divide each side by '2'.
x = -6.5
Simplifying
x = -6.5
The rectangle with maximum area will actually be a square.
Each side will be of length 7/4 = 1 3/4.
