The answer is 53
——————————-
To solve that we first need to write it as an equation where x is the number:
85 + x^2 = (x-17)^2
85 + x^2 = x^2 - 34x + 289
Now organize the equation by gathering like terms in the same side lf the equation:
You can shift 85 to the other side by subtracting 85 from both sides of the equation:
85 - 85 + x^2 =x^2 34x +289 - 85
x^2 =x^2 + 34x +204
And shift x^2 to the other side by subtracting x^2 from both sides:
x^2 - x^2 =x^2 -x^2 + 34x +204
0 = 34x + 204
Shift 34x to the other side by subtracting 34x from sides
-34x = 34x - 34x + 204
-34x = 204
And now isolate x by dividing both sides of the equation by -34
-34/-34x = 204/-34
x = -6
Thats your awnser , the number is -6

Answer:
The approximate lateral surface area of the cone is 251.2 m^{2}
Step-by-step explanation:
we know that
The lateral area of a cone is equal to
LA=(pi)(r)(l)
we have
r=16/2=8 m -----> the radius is half the diameter
l=10 m ----> the slant height
pi=3.14
substitute the values
LA=(3.14)(8)(10)=251.2 m^{2}
