Answer:

100 units^2

Step-by-step explanation:

a^2+b^2=c^2

8^2+6^2=c^2

64+36=c^2

100=c^2 (area of square)

10=c (length of hypotenuse)

Therefore, the area of the square is 100 units^2

Fill in the other coordinate for the line 2x−5y=11 (4, )
Gnesinka [82]

Basically you have to solve for the value of Y when x= 4

So you have -5y= 11 - 2x

                      y = -11/5 + 2/5x

therefore when x = 4 , y = -3/5

3(x - 5) = 6 solve the equation
pshichka [43]

____________________________________________________

Solve for x:

3(x - 5) = 6

Distribute the 3 to the variables inside the parenthesis

3x - 15 = 6

Add 15 to both sides to cancel out the "-15"

3x = 21

Divide both sides by 3

x = 7
