<h3><u>Explaination :</u></h3>
In the question it is given that the length is 4 cm more than the width so let us assume the width as x.
Therefore,
- Length (l) = 4 + x
- Breadth = x
As we know the formula of calculating the perimeter of rectangle is,
Here,
- P is perimeter
- l is length
- b is breadth
Putting their respective values,
=> 14 = 2 (x + 4 + x)
=> 14 = 2 × (x + 4 + x)
=> 14 = 2x + 8 + 2x
=> 14 = 4x + 8
=> 14 - 8 = 4x
=> 4x = 6
=> x = 6 / 4
=> x = 3 / 2
=> x = 1.5

Hey again...
So the first angle is angle C.
The first side is FC
and the second side is CG.
There you go and hope this helps!
Answer:
she has 12 - D quarters.
She has 24 (12-D) cents in quarters
Step-by-step explanation:
You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.
If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.
and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.
F(x)= (x+13)(x-2) in expanded form, it would be x^2+11x-26
