Erin was completing the square of the quadratic function in order to find the extreme value. What is the next step in the proces
Lady bird [3.3K]

Step-by-step explanation:

ax^2+bx+c=0

a=leading term

ok so if the leading term is positive then opens up and has a <u>min</u>

if leading term is negative then opens down and has a <u>max</u>

leading term is positive

1x^2+8x

it has a min

to complete the square, move c aside take 1/2 of b and square it

b=8

8/2=4

4^2=16

now add that to both sides

x^2+8x+16+6=0+16

factor perfect square

(x+4)^2+6=16

subtract 6

(x+4)^2=10

subtract 10

(x+4)^2-10=0

vertex aka min or max is (h,k) when ou have

y=a(x-h)+k

h=-4

k=-10

Surface area of a 4m and 4m and 4m cube
jeka94

Answer: 96 m²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a 3-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area so we can simply find the area of one face of a cube and multiply by the number of faces which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square which is S².

Since the length of a side is 4 meters, we have (4 m)² or 4 meters x 4 meters which is 16 m².

Now, since there are six sides to a cube, we have 6 (16 m)² which is equal to 96 m². So the surface area of the cube is 96 m².
