Answer:

Option C is correct.

Step-by-step explanation:

y = x^2+4x+5

We need to find the vertex of the above equation.

The above equation represents the parabola.

The slope of parabola can be found by taking derivative of the given equation

dy/dx = 2x+4

The slope of the parabola at the vertex is zero SO,

2x+4 = 0

2x = -4

x = -4/2

x = -2

Putting value of x =-2 to find the value of y

y = x^2+4x+5

y =(-2)^2+4(-2)+5

y = 4-8+5

y =9-8

y = 1

So, the vertex is (-2,1)

Option C is correct.

Answer:

135 degrees

Step-by-step explanation:

(8x-7)+(12x+57)=180

combine like terms

20x+50 = 180

subtract 50 on both sides

20x = 130

divide by 20

x = 130/20

x = 13/2

x = 6.5

cpq = 12x+57

cpq = 78 + 57

cpq = 135
