Answer:
L = 22 ft
Step-by-step explanation:
Let L and W represent the length and width respectively.
L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.
Area of a rectangle: A = L · W
Here, A = L · L/4 = 121 ft²
Mult. both terms by 4 removes the fraction:
L² = 484
Finding the square root of this result: L = 22
The length of the rect. is 22 ft.
Well if you add all the numbers together, the total is 14. So 4/14 chance of pulling out a red marble.
Q and S
Since this would be a dilation of 2
620 is the initial amount a, the growth factor b is 7.8, and the time is x.
Step-by-step explanation:
on applying ,
(a+b)²=a²+2ab+b²
So, c = 25 or (5)²
