A=a+b

2h=3+5

2·7=28

Step-by-step explanation:

Hope this helps

20 square yards

Step-by-step explanation:

I) Use formula for area:

A = ((a + b) / 2) * h

A = ((3 + 7) / 2) * 4

II) Solve:

A = (10 / 2) * 4

A = 5 * 4

A = 20

III) Final answer (with unit):

Our final answer is that the area of the trapezoid is 20 square yards, or 20 yd^2.

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.

all it means is function 3
