Answer:
A 1759 sq. units
Step-by-step explanation:
to find the surface area of a closed cylinder the formula is
2πr² + πdh
r = radius = 10
d = diameter = 10 + 10 = 20
2 x 3.14 x 10² + 3.14 x 20 x 18
628.3 + 1130.94 = 1759.24
ans = 1759
It is skewed to the right because 25 is the outlier.
3 out of 7 would be the answer
Answer: -5x³ + x² + 4x + 8
Step-by-step explanation
This is a polynomial expressions of third order.
The equation
(-4x³ + x² ) + (- x³ + 4x + 8)
Adding them together according to their order, we now have
( -4x³ + (-x³) + x² + 4x + 8 )
-4x³ - x³ + x² + 4x + 8
-5x³ + x² + 4x + 8
