Answer:
<h2>
70cm/s</h2>
Step-by-step explanation:
Area of a square with side of length L is expressed as A = L². The rate at which the area is increasing will be expressed as dA/dt.
dA/dt = dA/dL * dL/dt where
dL/dt is the rate at which each side of the square is increasing.
Since dA/dL = 2L, dA/dt = 2L dL/dt
Given dL/dt = 5cm/s and the Area of the square = 49 cm²
49 = L²
L = √49
L = 7cm
dA/dt = 2(7) * 5
dA/dt = 14*5
dA/dt = 70cm/s
The rate at which the area of the square is increasing is 70cm/s

The expression you would need to know how many games Chris sold is:
(504 divided by n) -17
If 2a−b/6 = b/3, then ratio a:b = 3 : 2
<h3><u>Solution:</u></h3>
Given that 2a−b/6 = b/3
We have to find the ratio of a:b
In mathematics, a ratio indicates how many times one number contains another
A ratio between two or more quantities is a way of measuring their sizes compared to each other
let us first solve the given expression

On cross multiplication we get,
6a - 3b = 6b
6a = 6b + 3b
6a = 9b

To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number
Therefore ratio a:b = 3 : 2
