Maria said 7•3=21.connie said 3•7=21.who is correct? explain.

Maria and Connie are both correct because 7×3=21 and 3×7=21 too they just switched the places but they are both correct hope this helped

Step-by-step explanation:

They are both correct

Step-by-step explanation:

3 times 7 will equal 21

and if you flip it its just 7 3's that also add up to be 21

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.

no
