Step-by-step explanation:

One side 6 by 8 = 48 Two sides = 96

The bottom 4 by 8 = 32

one end = 1/2(bh) 2( ends = bh = (4)(4)(√2) = 22.6 add all three numbers

h = √(6² - 2²) 1.414 = 151.6 Answer A 151

= √(36 - 4)

= √32

= √((16)(2))

h = 4√2

If you distribute, then you get -10x+7.5

Note how -2.5 times 4x = -10x and how -2.5 times -3 = 7.5

The idea is that you multiply the outer term (-2.5) by each term inside

Answer:

$(x-2)^2+(y+3)^2=4$

Step-by-step explanation:

A circle's equation consist on the following expression: $(x-a)^2+(y-b)^2=r^2$ , where r is the magnitude of the radio, and (a,b) are the coordenates of the center of the circle.
In this case, a=2 and b= - 3, because the circle is centered in (x,y)=(2, - 3).
The radio, which is the distance between the center of the radio to any point in its border, equals r=2 (because of the scale of the graphic, in this case two squares of the grid equal 2 units, then r=2).
Finally, using the previous information to replace in the equation $(x-2)^2+(y+3)^2=4$ , where the fact that r=2 and $2^2=4$ was used.
