8 0

Answer:

The correct option is B). 2x^{2}+16x+10

Step-by-step explanation:

Given function is (2x+4)^{2}-(2x^{2} +6)

On simplifying,

=(2x+4)^{2}-(2x^{2} +6)

=[4x^{2}+16x+16]-(2x^{2} +6)

=4x^{2}+16x+16-2x^{2}-6

Math question: Write the equation of the line with an undefined slope, passing through the point (2, 5).
lana [24]
When an equation has a line with an undefined slope, it means that the line is vertical. 

(2,5); 2 is the x - coordinate and 5 is the y - coordinate

Slope -  intercept form: y = mx + b

As shown above, the equation would've been written in slope - intercept form, where 'm' represents the slope and 'b' represents the y - intercept. However, in this case, the slope is undefined.
In the equation, you are ONLY looking for the x - intercept. Therefore, the x - intercept is 5, so that may be the equation of the line.

x = 5

When 50% of a number is added to the number, the result is 195.<br> What is the number?
olasank [31]

Answer:

The required number is 130

Step-by-step explanation:

Let the number be x

Given :-. 50% of a number ( 50% of x ) is added to the number ( x ) the result is 195.

50\% \: of \: x \:  + x = 195 \\  \\  \frac{50}{100}  \times x + x = 195 \\  \\  \frac{1}{2} x + x = 195 \\  \\  \frac{3}{2} x = 195 \\  \\ x = 195  \times  \frac{2}{3}

x = 130 !
