Which number sentence is true?

a. 3(p-q) = 3(q-p)
b. 3 + (p x q) = (p x q) + 3
c. (3 + p) - q = 3 + (p -q)
d. 3 ÷ (p + q) = (p + q) ÷ 3

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
