Which statement about 4+2x is true 1 The coefficient of x is 4
2 There are two variables in 4+2x
3 4+2x is a sum
4 4+2x is a product

4+2x is a sum.

Step-by-step explanation:

It can't be 1, because the coefficient of "x" is 2.

It can't be 2, because there aren't two variables in 4+2x. The only variable is x.

It can't be 4, because 4+2x is ADDING, not multiplying.

There we go!

5x+2x=49

7x=49

x=7. 35 apples

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.
