Answer:
-3y-3/4+7y+1/4-3x
I hope It's the right answer!
You solve for x
start by expanding the (3x-7)²
12 = 2(3x - 7)(3x - 7) + 4
12 = 2(9x² - 42x + 49) + 4
multiply the 2 through
12 = 18x² - 84x + 98 + 4
combine all like terms, set equal to zero
18x² - 84x + 102 - 12 = 0
18x² - 84x + 90 = 0
use the quadratic equation
Where
a = 18
b = -84
c = 90
then x = 3 and 5/3
Answer:
77 degrees
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees, so you can form an equation:
Answer:
The force's magnitude will be: F = k·|a| with k being the spring's elastic constant and |a| is the absolute value of the displacement.
The direction can be any, as depends on the reference system you choose. If the reference system is directed in the opposite way of the elastic force, it will be negative, else positive, but in any case the elastic force will be directed towards the equilibrium position of the spring.
