What is the perimeter

This Pythagorean theorem

48 feet.

Step-by-step explanation:

The Pythagorean Theorem is:

Plug in the numbers accordingly (it already gives the hypotenuse, "c."):

Subtract 256 from both sides:

Take the square root of both sides:

b = 12

To find the perimeter, add all the sides together, like so:

20 + 16 + 12 = 48

P = 48 ft

Step-by-step explanation:

Use Pythagorean theorem to find b

b = √20² - 16² = √400-256 = √ 144

b = 12

Perimeter is the sum of all sides so P = 20+16+12

P = 48

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.
