Answer:
6 SQUARE CENTIMETERS
Step-by-step explanation:
It's pretty easy you just add it
but with different shapes you can multiply but fo this its 6

2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)
another way to do it:
f(x)=x²-10x+16
the vertex is when x=-

, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
