Answer:

y=45000(1-0.03)^x

Step-by-step explanation:

Find x<br> (4+25)<br> (6x+20)<br> (3x+25)
ASHA 777 [7]

Answer:

x = 15

Step-by-step explanation:

the opposite angle of a cyclic quadrilateral sum to 180° , then

6x + 20 + 3x + 25 = 180

9x + 45 = 180 ( subtract 45 from both sides )

9x = 135 ( divide both sides by 9 )

x = 15
