Answer:
f(4)=5
Step-by-step explanation:
f(x)=x^2-6x+13
f(4)=4^2-6(4)+13
f(4)=16-24+13
f(4)=5
Answer: 
Step-by-step explanation:
Formula: Volume = 
a is the length of the base's edge and h is the height. Since 16 is the length we would square it as it is the length, then we would multiply it by the height which is 20 ft.

Answer:
14 litre
Step-by-step explanation:
1 week = 7 days
in 1 day holly drinks 2 L water
here, 7*2=14
2x + y = 3
x = 2y - 1
solve for y in the first equation;
2x + y = 3
y = 3 - 2x
x = 2y - 1
x = 2(3 - 2x) - 1
x = -4x + 5
solve for x;
x = -4x + 5
x + 4x = 5
5x = 5
x = 1
solve for y;
y = 3 - 2x
y = 3 - 2(1)
y = 1
the answer is: x = 1, y = 1
hope this helps, God bless!
