Answer:
Length = 4 feet
Width = 4 feet
Step-by-step explanation:
The perimeter of a rectangle formula = 2L + 2W
Where L = Length
W = Width
The length of a rectangle is 8feet less than the width.
Hence,
L = 8 - W
The perimeter is 64 feet.
Hence,
64 = 2(8 - W) × 2W
64 =( 16 - 2W )2W
64 = -4W² + 32W
4W² - 32W + 64 = 0
Factorise
4W² - 16W - 16W + 64 = 0
4W (W - 4) - 16(W - 4) = 0
W - 4 = 0
W = 4
Width = 4
Solving for L
L = 8 - W
L = 8 - 4
L = 4
Therefore,
Length = 4 feet
Width = 4 feet
When divided by 5, 3 subtracted from x divided by 2 equals to 6
Answer:
+ 3x +9x +27 = 0
x(x+3)+9(x+3)=0
(x+3)(x+9)=0
x=-3, x=-9
Step-by-step explanation:
a=1 b=12 c=27
sum=12
factor=27x 1
3x9
also 3+9=12
Answer:
