<h2>
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
Answer:
10 + 20 = 30
Step-by-step explanation:
If you subtract 5 from 25 you get 20 which is the length distance from b to c. Let's do the same to 15, 15 - 5 = 10. So now let's add our given lengths: 10 + 20 = 30.
