<em>now, note that if this was actually subtracting, logically, the answer would be H = 0</em>
<em>however, this is an addition problem, meaning to add a negative and a positive integer to get a negative integer.</em>
(3t^2 + 2 + (-2)) + (t^2 + 3t - 4) - (4 + (-5))
Apply the distributive property to remove parentheses.
3t^2 + 2 - 2 + t^2 + 3t - 4 - 4 + 5
Combine like terms.
<h3>4t^2 + 3t - 3 is the simplified form of the given expression.</h3>
It is a square based pyramid where,
Length (l)=9
Height (h)=10
Slant height (s)=11
For, volume (V) = 1/3 l^2*h
=1/3 9^2*10
=1/3 *810
=270
For, surface area = 2sl
= 2*11*9
=198
