7) Write and solve the equations. Make sure to answer the question asked. a) When 2,248 is subtracted from twice a certain number, the result is 10,000.
What is the number?
b) If you add one-third of a number to the number itself, you get 1348. What is
the number?
c) The sum of two consecutive odd integers is 244. What is the smaller integer?

piece?

answer is more than one

step-by-step explanation:

answer:     true

step-by-step explanation:

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.
