Round 1.625 to the nearest tenth

1.6

Step-by-step explanation:

the number 6 is one place after the decimal so it's where the tenth is, and the number after is 4 or below which in this case is 2 so the number rounds down to 1.6

1.6 hope this helps :)) !!

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.

stops on an even number.
