Answer:
She could have subtracted 19 from both sides. Hope this helps :)
Step-by-step explanation:
Hello :
the circumference of a circle is P : P = <span>2π×r r : ridus
</span> P = 2π×r = π× L because : 2r = L
you can find the diameter L : L = P/π
Answer:
Area of a Circle = πr²
R=Diameter/2
=21mm
=π(21)²
=1385.44mm²
To the nearest whole number
= 1385mm²
The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.

Answer:
2
Step-by-step explanation:
The correlating sides are similar meaning;
8/x = 16/4
using cross multiplication you will get;
16x = 32
which simplifies to;
x = 2
(f/g)(x) = (x^2-25)/(x-5) = x+5. So domain will be R, all real numbers
