17-(-15)=32
17-0=0
They are not equivalent so they are different.
Also for future reference when you have 2 minus signs they equal a addition sign.
Hope this helps :) GL

What is the area of the rectangle shown on the coordinate plane?
PolarNik [594]

The area of the rectangle is 42 units

The formula for calculating the area of a rectangle is expressed as:

  • A = length * width

From the figure, we will use the formula for calculating the distance between two points as shown:

For the length, we will use the coordinate points (5, 2) and  (2, -1)

Length  = √(-1-2)² + (2-5)²

Length = √9 + 9

Length = √18 = 3√2

Similarly for the width, we will use the coordinate points (5, 2) and  (12, -5)

Width  = √(-5-2)² + (12-5)²

Length = √49 + 49

Length = √98 = 7√2

Area of the rectangle = 3√2 * 7√2

Area of the rectangle = 42 units

Hence the area of the rectangle is 42 units

SO i need help urgently. 15 points!
Aloiza [94]

Answer:

-a² + 2ab + b² is your answer, or C).

Step-by-step explanation:

b(a + b) -a (a - b)

Distribute b to (a + b), and -a to (a - b)

b(a + b) = ab + b²

-a(a - b) = -a² + ab

Simplify. Combine like terms.

(-a² + ab) + (ab + b²) = -a² + 2ab + b²

-a² + 2ab + b² is your answer, or C).
