Evaluate the following expression using the values given:

Find -a2 - 3b3 + c2 + 2b3 - c2 if a = 3, b = 2, and c = -3.

Evaluate the following expression using the values given:

Find 3x2 - y3 - y3 - z if x = 3, y = -2, and z = -5.

could really use help with these two much appreciated

plug them in

debbieg · Answer

Plug & chug, e.g.:

for the first one, put in a = 3, b = 2, and c = -3, in:
 $\large -a^2 - 3b^3 + c^2 + 2b^3 - c^2 $

 $\large -3^2 - 3(2)^3 + (-3)^2 + 2(2)^3 - (-3)^2 $

Now evaluate that. Exponents first, then multiplication, then addition/subtraction.

Do similiarly for the other one.
