Just multiply Base x Height and you'll get your answer

Answer: sqrt(20)</h3>
=========================================
Explanation:
Count out the spaces, or use subtraction, to find the horizontal side BC is 2 units long. Similarly, you'll find the vertical side AC is 4 units long.
Use the pythagorean theorem to find the length of segment AB.
a^2 + b^2 = c^2
2^2 + 4^2 = c^2
4 + 16 = c^2
20 = c^2
c^2 = 20
c = sqrt(20)
We stop here since it matches with choice B.
-----------------
Optionally, we can simplify like so
sqrt(20) = sqrt(4*5)
sqrt(20) = sqrt(4)*sqrt(5)
sqrt(20) = 2*sqrt(5)
Answer:
3x²-3x+2
Step-by-step explanation:
To find A-B:
Substitute A and B with given values:
x²-(-2x²+3x-2)
Epand the bracket since there is a -1 in front of the bracket (the 1 is invisible)
x²+2x²-3x+2
Simplify:
3x²-3x+2
