The cost of admission at a carnival is $5 and the cost to play a game is $3. the expression 3g+5 represents the total cost for admission and playing games. evaluate the expression when g=13

the total cost when g=13 is $44

Step-by-step explanation:

3g+5= total cost

g=13

substitute for g

3(13)+5= total cost

Multiply

39+5= total cost

add the numbers together

44 = total cost

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.
