A rectangle is 12 cm long and 9 cm wide. Its diagonal is labeled 2x - 11. What is the value of x?
shusha [124]

Answer: The value of x is 13 cm.

Explanation:

It is given that the length and width of the rectangle are 12 cm  and 9 cm.

Use pythagoras to find the value of the diagonal.

Hypotenuse=\sqrt{(base)^2+(perpendicular)^2}

D=\sqrt{(12)^2+(9)^2}

D=\sqrt{144+81}

D=\sqrt{225}

D=15

It is given that the diagonal is labeled as 2x-11.

2x-11=15

2x=15+11

2x=26

Divide both side by 2.

x=13

Therefore, x = 13cm.

Are the associative properties true for all integers
Ymorist [56]
Associative property works in addition and multiplication.
Associative property in Addition: (a + b)+ c = a + (b + c)
Associative property in Multiplication: (a x b) x c = a x (b x c)
Associative property in Subtraction: (a - b) - c is not equal to a - (b - c)
Associative property in Division: (a divided by b) divided by c is not equal to a divided by (b divided by c).
Thus, associative property is not true for all integers.
