Answer:

12 units squared

Step-by-step explanation:

You need to find the area of each individual shape, and then add them together. The area of the square is 4 units squared. The triangle on the left is two units squared (base times height, divided by two,) and the area of the triangle on the left is 6. Add them all together, and you get 12 units squared.

Solve the equation for x, where x is a real number (5 points): <br> -3x^2 + 6x + 9 = 7

lana66690 [7]

Add -7 to both sides so that the equation becomes -3x^2 + 6x + 2 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                                       x = [ -b ± √(b^2 - 4ac) ] / (2a)
                                       x = [ -6 ± √((6)^2 - 4(-3)(2)) ] / ( 2(-3) )
                                       x = [-6 ± √(36 - (-24) ) ] / ( -6 )
                                       x = [-6 ± √(60) ] / ( -6)
                                       x = [-6 ± 2*sqrt(15) ] / ( -6 )
                                       x = 1 ± -sqrt(15)/3
The answers are 1 + sqrt(15)/3 and 1 - sqrt(15)/3.

Which of the following graphs is a polynomial function with x-intercepts of (-3,0)(-1,0), and (2,0)?

Helen [10]

The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
