The average length of a King Cobra is 118 inches, which is 22 inches longer than the black mamba. Write and solve an addition eq
TiliK225 [7]
I think it would be:

22 + x = 118 for your equation.

And then to solve, it would be:

22 + x = 118
-22 -22

x = 96

Average length of black mamba = 96 inches

However it is late where I am so my bad if that’s not what you needed

Which figure shows a reflection of pre-image DEFG over the x-axis?
Sergio [31]
The image that shows the reflection of DFEG over the x-axis is the FIRST option. The x-axis is the mirror line. The distance from the mirror line to the reflected shape equals to the distance from the original image to the mirror line.

Which of the following are solutions to 2x2 – 8x - 90? Select all that apply.
Bond [772]

Answer:

x=-5, x=9

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

2x^{2} -8x-90  

equate to zero

2x^{2} -8x-90=0  

so

2=-1\\b=-8\\c=-90

substitute in the formula

x=\frac{-(-8)\pm\sqrt{-8^{2}-4(2)(-90)}} {2(2)}

x=\frac{8\pm\sqrt{784}} {4}

x=\frac{8\pm28} {4}

x=\frac{8+28} {4}=9

x=\frac{8-28} {4}=-5

therefore

The solutions are x=-5, x=9
