Step-by-step explanation:

5 {x}^{2}  - 40x + 80 \\  =5( {x}^{2} - 8x + 16) \\  = 5 ( {x}^{2}   - 8x +  {4}^{2}  ) \\  = 5 {(x - 4)}^{2}

Answer:

\boxed{\sf \ \ \ 5(x-4)^2 \ \ \ }

Step-by-step explanation:

hello

step 1 - divide by 5

5x^2-40x+80=5(x^2-8x+16)

step 2 - solving the square

(x-4)^2=x^2-8x+16

Finally, to answer the question

5x^2-40x+80=5(x-4)^2

hope this helps

Find the midpoint of side EF. (4 points)
umka2103 [35]

Answer:

Midpoint of side EF would be (-.5,4.5)

Step-by-step explanation:

We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:

e=a+c/2,f=b+d/2

Here we have to find the mid-point of side EF.

E(-2,3) i.e. (a,b)=(2,3)

and F(1,6) i.e. (c,d)=(1,6)

Hence, the coordinate of midpoint of EF is:

e=-2+1/2, f=3+6/2

e=-1/2, f=9/2

e=.5, f=4.5

SO, the mid-point would be (-0.5,4.5)
