$900+ $288( interest after 8 years)= $1, 188( total balance)
72 square feet
EXPLANATION: when finding area of a rectangle, multiple Length x Width and 6x12=72
14 = 9 - x
First, subtract 9 from both sides.
14 - 9 = (9 - 9) - x
5 = -x
Now divide both sides by -1.
5/-1 = -1/-1x
-5 = x
The answer is x = -5.
X^2+x+8 is the answer unless you need it factored
Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
