The answer is 21 m squared
3(5)=15
3(2)=6
15+6=21
If it gives you your total, and another number, divide the 2
example:
25 • x = 75
75/25= 3
x=3
Answer:
I'm pretty sure it's the first one
9514 1404 393
Answer:
48
Step-by-step explanation:
The Pythagorean theorem tells you the square of the hypotenuse (longest side) is the sum of the squares of the other two sides. Let x represent the unknown side.
73² = x² +55²
5329 = x² +3025 . . . evaluate the squares
2304 = x² . . . . . . . . . subtract 3025 from both sides
48 = x . . . . . . . . . . . . take the square root of both sides
The exact length of the third side is 48.
