<span>Let y= original side
So
A = LW
60 = (y+15)(y-13)
(y+15)(y-13) = 60
y^2 + 2y - 195 = 60
y^2 + 2y- 195 - 60 = 0
y = -17 or y= 15
Toss out the negative solution to get y= 15 as the only solution.
So the square has a side length of 15 meters.
The area of this square is 15^2 = 15*15 = 225 square meters.</span>

I'm doing a challenge. This is my answer. IDK.
Step-by-step explanation:
Answer:
53.13°
Step-by-step explanation:
Using Sine rule
b / Sin B = a / Sin A
5/ Sin90 = 4 /Sin A
5/1 = 4 /SinA
Sin A = 4/5
A = arc sin(0.8)
A = 53.13010
A = 53.13 °
Answer:
The expanded form of the expression 
is 
Step-by-step explanation:
We need to write expanded form of the expression
For expansion we will use distributive property of multiplication over addition
Applying above rule:
So, the expanded form of the expression is
The correct answer to place y minus 12 in an algebraic expression is simply
y - 12
