Associative property is where you can switch the place of the digits and it still have the same answer in the end.
You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
Answer:
2 (real) solutions.
Step-by-step explanation:
A quadratic always has two solutions, whether they are real or complex.
Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).
In the case of
x^2+3x = 3, or
x² + 3x -3 = 0
we apply the quadratic formula to get
x = (-3 +/- sqrt(3^2+4(1)(3))/2
to give the two solutions
{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}
both of which are real.
263.25 is the volume of the box in inches cubes you have to multiply 4.5 by 9 by 6.5
Answer:
C. -5
Step-by-step explanation:
