2 1/2 + 3 2/3 + 1 7/9 = ANSWER ASAP AND BE RIGHT
EXPLAI STEP BY STEP
TO BE BRAINLIEST

Step-by-step explanation:

Fractions are easier to add when in improper form.

2 1/2 = 5/2

3 2/3 = 11/3

1 7/9 = 16/9

Now, we need to find a common denominator for these fractions.

18 is a multiple of 2, 3, and 9, so we can use it.

Convert all the fractions to have 18 as denominator:

5/2 = 45/18 (multiply by 9)

11/3 = 66/18 (multiply by 6)

16/9 = 32/18 (multiply by 2)

Now that all the fractions are converted to having the same denominator, we can add them.

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.
