Answer:
D 4.5
..........................................
1. You have the following information:
- <span> The square has the same area as a rectangle.
- The dimensions of the rectangle are: 14 mm long and 16 mm wide.
2. You must use the formula for calculate the area of a square, which is shown below:
A=S</span>²
"A" is the area of the square.<span>
"S" is the lenght of the side of the square. (It is important to remember that the sides of a squre have equals lenghts.
3. The square and the rectangle have the same area. Therefore:
Arectangle=(14 mm)(16 mm)
Arectangle=224 mm</span>²
<span>
A=224 mm</span>²
<span>
4. Now, you must substitute the value A=224 mm</span>² into the formula A=S² and clear "S":
<span>
A=S</span>²
<span> S=</span>√A
<span> S=</span>√(224 mm²)
<span> S=15 mm
The answer is: 15 mm

Answer:
x - y = - 1
Step-by-step explanation:
Given the 2 equations
5x + 4y = 13 → (1)
4x + 5y = 14 → (2)
Subtract (2) from (1) term by term , that is
(5x - 4x) + (4y - 5y) = 13 - 14
x - y = - 1
