Ali rented a truck for one day. there was a base fee of $18.99, and there was an additional charge of 78 cents for each mile driven. ali had to pay $146.91 when he returned the truck. for how many miles did he drive the truck

164

Step-by-step explanation:

146.91-18.99= 127.92

127.92/0.78= 164

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.
