Answer:

- (x - 4 {)}^{2}

Step-by-step explanation:

The given expresion is

-  {x}^{2}  + 8x - 16

Factor -1;

- ( {x}^{2}  - 8x + 16)

Split the middle term with -4x-4x

- ( {x}^{2}  - 4x - 4x + 16)

Factor by grouping within the parenthesis:

- ( x({x}  - 4)- 4(x  - 4) )

Factor further:

- (x - 4)(x -4 )

- (x - 4 {)}^{2}

This the opposite of the square of (x-4)

Which ratio is greater, 4:5 or 3:4?
Grace [21]
4:5
explanation-

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

How do I get from: <br>Sin x = -1/2<br>To: x = 7Pi/6, 11Pi/6
brilliants [131]
A few ways. you can enter it into a calculator for one, but the easiest way would be to reference a unit circle and look for an ordered pair where sin (the y value), is equal to -1/2

on a unit circle, the sin value is -1/2 at 7pi/6 and 11pi/6

because sin is the y value, it will additionally be in the quadrants III or IV based on the fact that (-1/2) as a sin value IS a negative and would have to be found in a quadrant in which sin is negative (the lower half of a coordinate plane, in this case)
