Answer:
x=4.375
Step-by-step explanation:
-3(2x-7)+5=2x-9
-6x+21+5=2x-9
-6x+26=2x-9
-6x-2x+26=2x-2x-9
-8x+26=-9
-8x+26-26=-9-26
-8x=-35
-8x/-8=-35/-8
x=4.375
The area of a sphere: A = 4.π.R²
A= 5541.77 → 5541.77 = 4.π.R²
R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm
I think it represents where something is starting from, like something growing up (a chart with rising numbers)
