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
x | y
-
2 | 10
4 | 20
6 | 30
just plug the x values (2,4,6) into x in the equation and you get your y! example would be y=5(2) so y=10
First one is 3/8>1/3
Second one is B
Third one is C
Fourth one is B
Answer:
1550
Step-by-step explanation:
1250-(-300) <-- positive due to two negative
1250+300
1550
Answer:
Final amount after 4 years will be $5518.
Step-by-step explanation:
From the given question Principal amount in the account of Stan = $4706
and we have to calculate amount after 4 years with 4% interest compounded quarterly.
Formula will be final amount 
Here A' = $4706
t = 4 years
n = number of times compounded = quarterly that will be 4
r = .04
So the final amount after four years will be $5518.
