Answer: It costs $5.52 to Sam to buy 12 stamps.

Step-by-step explanation:

Given: Sam paid $8.28 for 18 stamps.

Thus, the cost of 18 stamps = $8.28

Then the cost of 1 stamp= $\frac{8.28}{18}$

Thus, the cost of 1 stamp=$0.46

With the same rate , the cost of 12 stamps= $0.46\times12$

Therefore, the cost of 12 stamps= $5.52

hence, it costs $5.52 to Sam to buy 12 stamps.

The graph shows the system of equations that can be used to solve x^3+x^2=x-1.Which statement describes the roots of this equati

Answer:

Equation has one real root and two complex roots.

Step-by-step explanation:

The equation $x^3+x^2=x-1$ consists of two parts. The left side of this equation can be represented by the function $y=x^3+x^2$ and the right side can be represented by the function $y=x-1.$ Graphs of both these functions are shown in the attached diagram.

These graphs have one common point, this means that the equation $x^3+x^2=x-1$ has one real solution (approximately, x≈-1.839).

Given equation is cubic, then this equation has three roots. Since only one root is real, then two remaining roots are complex.

Answer:

$x=\sqrt{14}$

Step-by-step explanation:

This triangle is a 45-45-90 triangle.

By using the image I posted, we can find x easily.

So, we have $\sqrt{7}$ as one of the sides.

They hypotenuse, which is x is just $\sqrt{7} \sqrt{2}$

Simplify and we get x = $\sqrt{14}$

The answers are 3 and -13

You need to plug 3 and -5 into x

By doing this, you get :

12 - 3^2 and

12 - (-5)^2

those expressions equal

12 - 9

12 - 25

So you get

-13
