Answer:

k^2 -3k +9/2

(k-3/2)^2

Step-by-step explanation:

k^2 -3k

Take b/2 and then square it to find the term to complete the square

(-3/2) ^2 = 9/4

k^2 -3k +9/2

The expression factors to (k-b/2)^2

(k-3/2)^2

The length of a rectangle is three times it's width. If the perimeter of the rectangle is 64, find its length and width
wlad13 [49]

set up an equation for the perimeter

l = length w = width

2l + 2w = 64

set up another equation as you know the length is 3 times the width

w = 3l

subsitute w = 3l into the 2l + 2w = 64

2l + 2(3l) = 64

solve for l

2l + 6l = 64

8l = 64

<em><u>length</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>

subsitute into w = 3l

w = 3(8)

<em><u>width</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em>

Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?
Rainbow [258]

Answer:

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )

Step-by-step explanation:

Midpoint of line segment is calculated as

m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )  -----------(1)

Here

(x_1, y_1) = (12,2) \ \  and \ \ (x_2, y_2) = (-5, -7)

Substituting values in equation (1)

m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )
