2 answers:
Answer:
Step-by-step explanation:
The model is showing that yellow boxes plus blue boxes gives a result of 5 orange boxes.
So, each yellow box represents , so, three of them would be
Each blue box represents , two of them would be

For the triangle, x is 12 units long.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse is the side which is the longest in the triangle and is always opposite the right angle.
In the given triangle, the hypotenuse is 13 units long. The other two sides measure 5 units and x units.
Step 2:
By substituting the known values, we get
Rounding this off to the nearest hundred, we get that x is 12 units long.
