The total area of the pyramid is the area of the square plus the area of the four triangles which is 62+62+62+62+(11*11)=369 cm2
By solving the linear equations we get the final values of x = 4 & y = 4.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order term are included.
We have,
2x + 7y = -20 ----------(i)
x - 3y = 16 ----------(ii)
By multiplying equation (ii) with 2 we get,
2x + 7y = -20 ---------(III)
2x - 6y = 32 -----------(IV)
taking subtraction of equations (III) and (IV), we get
y = 4
by putting value of y in equation (ii) we get,
x = 4
Hence by solving the linear equations we get the values of x = 4 & y = 4.

Answer:
2:3
Step-by-step explanation:
minutes per day on weekdays:minutes per day on weekends
90:135
It can be written in simpler form, because both numbers can be divided by 45
90÷2=45 and 135÷45=3
The ratio is 2:3.
A) 4 minutes
B) .25 laps per minute
C)36 minutes
Answer: X= 54.9 mm
Explanation: honestly I would never know how to do this and I don’t know how to do this I just put it into a triangle generator and it gave me the correct answer I promise its right
