Answer:

Area = 20 units²

Step-by-step explanation:

Let A(-8,-2), B(-3,-2), C(-3,-6) and D(-8,-6) so that the rectangle becomes ABCD.

=> Since it's a rectangle it will have two opposite sides equal.

So, let's find the length of any two sides (as length and width) by Distance Formula.

Distance Formula = $\sqrt{(x2-x1)^2+(y2-y1)^2}$

Side AB:

|AB| = $\sqrt{(-3+8)^2+(-2+2)^2}$

|AB| = $\sqrt{5^2}$

|AB| = 5

Side BC:

|BC| = $\sqrt{(-3+3)^2+(-6+2)^2}$

|BC| = $\sqrt{16}$

|BC| = 4

Now, Area:

Area of the rectangle = Length * Width

Area = 4 * 5

Area = 20 units²

What is the solution to the following system? 2y +x=4 y=-0.5x + 2

icang [17]

1) Input Y.
2(0.5x + 2) + x = 4

2) Distribute and combine like terms
= 2x + 4 = 4

3) Subtract 4 from both sides
2x = 0

4) Divide.
2x/2 = 0/2

x = 2

The sum of two numbers is 45 and the difference is 3. What are the numbers?

AVprozaik [17]

Answer:

24 and 21 are the two numbers

Step-by-step explanation:

let n represent the unknown number

let n-3 represent the second unknown number

n+n-3 = 45

2n-3=45

2n=45+3

2n=48

n=48/2

n=24

n-3=21

CHECK: 24+21=45

.˙. the first number is 24 and the second number with a difference of 3 is 21
