The area is 113.1m If you want to double check go on google and look up surface area of a sphere. A calculator will come up. Hope this helped.
Answer:
x^2 -10x+25
Step-by-step explanation:
(x-5)^2
Rewriting
(x-5)(x-5)
FOIL
first: x*x = x^2
outer: x* -5 = -5x
inner: -5*x = -5x
last: -5 * -5 = +25
Add them together
x^2 -5x-5x+25
Combine
x^2 -10x+25
Answer:
22
Step-by-step explanation:
0.8 --> 1 * 22 = 22
Hope this helped! Have a nice day!
a x=12
the sum of angles in a triangle is 180
53+39+4+7x=180
96+7x=180
7x=86
x=84/7
x=12
b. sum of angles in a triangle is 180
5x+(6x-5)+75=180
5x+6x-5+75=180
11x+70=180
11x=180-70
11x=110
x=110/11
x=10
that's how to solve it
