Answer:
31.6% decrease
Step-by-step explanation:
percent of change = difference between original and new values divided by the original value
n = % change
n = 0.72/2.28
n = .3157
n = 31.6%

Value of x is 2 </h2>
Step-by-step explanation:
Surface area is given by 2x²+48x+88
We need to find x when surface area is 192.
A = 2x²+48x+88
2x²+48x+88 = 192
2x²+48x- 104 = 0
x²+ 24x - 52 = 0
( x - 2 ) ( x + 26 ) = 0
x = 2 or x = -26 not possible
Value of x is 2
First write down your equation. 2(y-3)=1.2-y. the distribute your 2. 2 times y is 2y and 2 times -3 is -6. now you have 2y-6=1.2-y. bring your y to the other side of the equation with the opposite sign and do the same with your 6. you have 2y+y=1.2+6. combine the like terms and constants. now you have 3y=7.2. divide bother sides of the equal by 3 to get y alone. 3y/3= 7.2/3. your answer is y=2.4.
