Answer:

108 is your answer.

Step-by-step explanation:

1 x + 2x + 3x = 180

10 x = 180

x = 180/ 10

x = 18

Then

18 X 6 = 108

I HOPE IT WILL HELP YOU.

Have a great day.

In a cafeteria 3/10 of the students are eating salads, and 3/5 are eating sandwiches. There are 20 students in the cafeteria. Ho

Elanso [62]

We know that 3/10*20=6 students are eating salads.

We also know that 3/5*20=12 students are eating sandwiches.

Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.

I really need help with this. Can anyone help me please?

I am Lyosha [343]

Answer:

$f(x)=(x-3)(x^2+4x+8)$

Step-by-step explanation:

A polynomial function is given by the form:

$f(x)=a(x-p)(x-q)...$

Where a is the leading coefficient, and p and q are the roots (more can be added if necessary).

Our zeros are 3 and (-2 + 2i).

And our leading coefficient a = 1.

Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.

So, by substitution, we acquire:

$f(x)=1(x-(3))(x-(-2+2i))(x-(-2-2i))$

Simplify:

$f(x)=(x-3)(x+2-2i)(x+2+2i)$

Expand the second and third factors:

$\begin{aligned} &=(x+2-2i)x+(x+2-2i)(2)+(x+2-2i)(2i)\\&= (x^2+2x-2ix)+(2x+4-4i)+(2ix+4i-4i^2)\\&=(x^2)+(2x+2x)+(-2ix+2ix)+(-4i+4i)+(4-4i^2)\\&=x^2+4x+(4+4)\\&=x^2+4x+8 \end{aligned}$

Therefore, our polynomial function of least degree and the given zeros will be:

$f(x)=(x-3)(x^2+4x+8)$
