What expression represents the profit, and what is the profit if 240 cell phones are sold?
Profit is the difference between revenue and cost. The
revenue, in dollars, of a company that manufactures
cell phones can be modeled by the polynomial 2x2 +
55x + 10. The cost, in dollars, of producing the cell
phones can be modeled by 2x2 - 15x - 40. The
variable x represents the number of cell phones sold.
O40x - 30; $2,400
040x - 30; $9,570
O 70x + 50; $16, 850
O 70x + 50; $28,800

we need the options

step-by-step explanation:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

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.
