Carter plans to wallpaper the longest wall in his wall paper. the wall is twice as long as it is high and has a area of 162 feet. what is the height of the wall

9 ft

Step-by-step explanation:

The wall has the shape of a rectangle.  Let H represent the height of the wall.  Then, in terms of H, the length is 2H.  

The area of the wall is given:  162 ft.  This is equal to A = H(2H), or 2H^2.

Equating 162 ft and 2H^2, we get H^2 = 81, so that H must be 9 ft.

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
