You run 4 3/4 of a miles through a park each day if you ran that distance 5 times last week how many miles did you run

23 3/4

Step-by-step explanation:

you have to convert 3/4 to a decimal which would be .75 and your whole number is 4 so now you look at how many times you ran 4 3/4 miles and multiply 4.75 times 5 which would be 23.75 and u have to convert your decimal back into a fraction wich would make your answer 23 3/4

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.
