What is the area of the rectangle, in square feet?
9 ft
20 ft
A.29
B.58
C.120
D.180

9 x 20ft = 180

If one of those values 8ft and 20ft is the diagonal then we deduct the square of thise numbers being  √400 -   √81 =  √309 and find  √309 square of  17.57ft

17.57 x 9 = 158.13

so  √158.12 = 12.57

and  √162 = 12.72

But your question was just a case of finding how to do area and for that we use L x W to find area

A = 9 x 20 = 180ft^2

Step-by-step explanation:

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

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.
