A 60-foot long crane is parked in the right lane of a city street. The street is 30 feet wide. How high will the crane have to be raised in order to swing around from one end of its trailer to the other end without striking the building on the opposite side of the street?​

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.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
