The height of the chalkboard is 3ft. Since the chalkboard has a perimeter of 18ft, that means that the 2 lengths of the board are 6 ft or 12 ft added together. Afterwards, subtract 12 from 18 ft ( 18 - 12), which shall get you 6ft. Then, divide 6 by 2, since there are two sides that represent the height.

Therefore, the height is 3 ft.

P = 2H + 2L
L = 6
P = 18
18 = 2H + 2*6
18 = 2H + 12
6 = 2H
H = 3 ft

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

x_{vertex}= -b/2a

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

f(-13/4)= -9/8

Then your expression for this quadratic should be:

f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
