Step-by-step explanation:
.19 = 19/100
.864 = 86.4/100
.5348 = 53.48 /100
I multiplied the decimal by 100 to get what it was before which is the same as moving two decimal places to the right and divided by 100
if any confusion ask
Answer:

Then just plug in the values depending on the bridge you chose I'm pretty sure
also can I get brainliest?
The surface area will increase by a factor of 49/16
<span>x in (-oo:+oo)
((5-9*x)^1)/2 = ((4*x+3)^1)/2 // - ((4*x+3)^1)/2
((5-9*x)^1)/2-(((4*x+3)^1)/2) = 0
(5-9*x)/2-((4*x+3)/2) = 0
(5-9*x)/2+(-1*(4*x+3))/2 = 0
5-1*(4*x+3)-9*x = 0
2-13*x = 0
(2-13*x)/2 = 0
(2-13*x)/2 = 0 // * 2
2-13*x = 0
2-13*x = 0 // - 2
-13*x = -2 // : -13
x = -2/(-13)
x = 2/13
x = 2/13</span>
