Answer:

C

Step-by-step explanation:

The triangle is an equilateral triangle, which is equal on all three sides in both side length and angle. since one of them of 60 degrees, then all of them would also be 60 degrees. Since the total amount of degrees in a triangle is 180, 60*3=180 so the answer is C.

Answer:

Part A: There are 4 zeros of the polynomial function f(x)

Part B: The zeroes of the polynomial function f(x) are -4, -1, 0, 2 ⇒ C

Step-by-step explanation:

<em>The zeroes of a function are </em><em>the x-coordinates of the point of intersection between the graph of the function and the x-axis</em><em> (x-intercepts) which means </em><em>values of x at y = 0</em>

Part A:

In the given graph

∵ The graph of the function f(x) = -x^{4} - 3x³ + 6x² + 8x intersects the x-axis

   at 4 points

→ That means there are 4 values of x have y = 0

∴ The number of zeroes of the function is 4

∴ There are 4 zeros of the polynomial function f(x)

Part B:

∵ The graph intersects the x-axis at points (-4, 0), (-1, 0), (0, 0), (2, 0)

→ That means the values of x at y = 0 are -4, -1, 0, 2

∴ f(x) = 0 at x = -4, -1, 0, 2

∴ The zeroes of the polynomial function f(x) are -4, -1, 0, 2

liraira [26]

Answer:

Step-by-step explanation:

Length of the garden = 4 - 21*x - 28*y

Width of the garden = -6*x*y

Perimeter of the garden = 2*(Length + Width)

P = 8 - 42*x - 56*y - 12*x*y

What is the area of 2x+2 and 3x+2 of a square
KengaRu [80]

Answer:

6x^2 + 10x + 4 units of measurement

Step-by-step explanation:

The area of a square is L*W.

(2x+2)*(3x+2) = (6x^2) + (4x) + (6x) + (4)

                      = 6x^2 + 10x + 4
