Evaluate the expression m + p for m = 9 and p =7

16

Step-by-step explanation:

Step 1: Write out expression

m + p

Step 2: Define variables

m = 9

p = 7

Step 3: Plug in variables

9 + 7

Step 4: Evaluate

16

if you mean

then it's c. 8, -7/3

but if you mean

then it is

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
