Sharing = division. 16 divided by four is four. Now, each person gets a fourth so a fourth of four is 1/4. Each person gets 1/4.
2x² + 12x + 11 - (x - 4)²
2x² + 12x + 11 - 1(x - 4)²
2x² + 12x + 11 - 1(x - 4)(x - 4)
2x² + 12x + 11 - 1(x(x - 4) - 4(x - 4))
2x² + 12x + 11 - 1(x(x) - x(4) - 4(x) + 4(4))
2x² + 12x + 11 - 1(x² - 4x - 4x + 16)
2x² + 12x + 11 - 1(x² - 8x + 16)
2x² + 12x + 11 + 1(x²) + 1(8x) - 1(16)
2x² + 12x + 11 + x² + 8x - 16
2x² + x² + 12x + 8x + 11 - 16
3x² + 20x - 5
Answer:
1 - C
2 - A
3 - D
4 - B
Step-by-step explanation:
Consider an arbitrary function y=f(x).
1. f(x)>0 means y>0. y>0 determines all points on the graph which have positive y-coordinates. Positive y are corresponding to those x from the domain, for which graph lies above the x-axis. So 1 - C
2. f(x)<0 means y<0. y<0 determines all points on the graph which have negative y-coordinates. Negative y are corresponding to those x from the domain, for which graph lies below the x-axis. So 2 - A
3. To find y-intercept, we have to substitute x=0, so input is zero. Hence, 3 - D
4. To find x-intercept, we have to substitute y=0, so output is 0. Hence, 4 - B

<h2>Step-by-step explanation :</h2>
As we know, that all squares are quadrilateral but its converse is not necessarily true.
Set of Quadrilaterals is a super set of set of squares.
i.e. set of squares ≤ set of quadrilaterals.
From the picture, we can know that quadrilaterals consists of all the squares and square is a type of quadrilateral. All the squares belong to quadrilaterals, while not all the quadrilaterals belong to squares.

Answer:
angle YUT = 120
Step-by-step explanation:
in Triangle SUT
angle 70 + angle 50 + angle x = 180
70 + 50 + x = 180
120 + x = 180
x = 180 - 120
x = 60
angle SUT = 60
angle SUT + angle YUT = 180 ( straight line)
60 + x = 180
x = 120
Therefore angle YUT ( exterior angle ) = 120
