-2(3x+9)= 24
Distribute the 2 using the distributive property, which states: a(b + c) = ab + ac
-2(3x+9)= 24
-2(3x) + (-2)(9) = 24
Simplify it
-6x - 18 = 24
Add 18 on both sides
-6x - 18 + 18 = 24 + 18
-6x = 42
Divide -6 on both sides
-6x/-6 = 42/-6
x = -7
Your answer is x = -7.
Hope I helped! If you have any other questions or would like further explanation just let me know!! :)
add 18 for -6x=42 for -7 so your answer is x=-7

length = 22 cm; width = 18 cm
length = 24 cm; width = 16 cm
length = 23 cm; width = 14 cm

Answer:
Length = 25 cm , Width = 15 cm.
Step-by-step explanation:
Given : The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 80 cm.
To find : What are the dimensions of the rectangle.
Solution : We have given
Perimeter = 80 cm .
According to question :
Let width of rectangle = W .
Length is twice its width.
L = 2W .
Length of a rectangle is 5 centimeters less than twice its width.
L = 2W - 5.
Then ,
Perimeter = 2 ( length + width).
Plug the values
80 = 2 ( 2W - 5 + W ) .
80 = 2( 3W -5) .
On dividing both sides by 2
40 = 3W - 5 .
On adding both sides by 5.
45 = 3 W .
On dividing both sides by 3.
W = 15 cm .
L = 2W - 5.
L = 2 ( 15) - 5 .
L = 30 -5 .
L = 25 cm .
Therefore, Length = 25 cm , Width = 15 cm.
Answer A
Let's the width of the rectangle
2a-5 its length
Teh half perimeter is 80/2=40
a+2a-5=40 ==>3a=45==>a=15 and 2a-5=30-5=25

The variables a and b are,

What is mean by Function?
A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines relationship between one variable and another variable.
We know that;
For a hyperbola ;
⇒ x² / a² - y² / b² = c²
where, a² + b² = c²
And, The directrix is the line, y = a² / c
and, the focus is at (0, c).
Here, We have;
⇒ c = 5,
⇒ a² = 9,
So We get;
⇒ b² = 5² - 9 = 16.
Thus, We get;
⇒ a = √9 = 3
⇒ b = √16 = 4
