Answer:
Length: 84 ft
Width: 56 ft
Step-by-step explanation:
Let's define some variables first.
Call the length l and width w.
We know that w = 2/3l. Therefore, we can express w in terms of l with this expression.
Now, let's set up an equation. The flower garden is rectangular, and 280 feet of fencing are used to enclose the garden. This represents perimeter.
Remember the formula for perimeter of a rectangle: 2l + 2w
Let's substitute 2/3l for w:
2l + 2*2/3l = P
2l + 4/3l = 280
2 4/3l = 280
10/3l = 280
l = 84
Now, we know that the length is equal to 84 feet. We can multiply 84 feet by 2/3 to find the width.
84*2/3 = 56
Length: 84 ft
Width: 56 ft
Let's plug these values into the formula and see if they give us the correct perimeter:
2l + 2w = P
2*84 + 2*56 = P
168 + 112
= 280 feet
These are the correct dimensions!

Answer
given equation,
x⁵²-21 x+20
A number to be divisible by the another number means that on dividing the remainder should be zero.
if x⁵²-21 x+20 is divisible by x− 1 means that x-1 should completely divide the equation.
so,
x -1 = 0
x = 1
x⁵²-21 x+20 to be divisible it should be equal to zero when x = 1
putting x = 1
= (1)⁵²-21 (1)+20
= 1 - 21 + 20
= 21 -21
= 0
hence x = 1 is the root of the equation
so, x⁵²-21 x+20 is divisible by x− 1.

48 cookies after 25 % decrease is as much as 75 % from 48:
75% from 48 =
= 75/100 * 48 =
= 3/4 * 48 =
= 3/1 * 12 =
= 3 * 12 =
= <u>36
