Answer: {x,y}={-1,2}
step-by-step explanation:
// Solve equation [2] for the variable x
[2] 2x = 5y - 12
[2] x = 5y/2 - 6
// Plug this in for variable x in equation [1]
[1] 2•(5y/2-6) + 3y = 4
[1] 8y = 16
// Solve equation [1] for the variable y
[1] 8y = 16
[1] y = 2
// By now we know this much :
x = 5y/2-6
y = 2
// Use the y value to solve for x
x = (5/2)(2)-6 = -1
Solution :
{x,y} = {-1,2}
Answer:
The answer to your question is 92.4 cm²
Step-by-step explanation:
Data
Side of a square = 6 units
Longest side of a rhombus = 10 units
Process
1.- Calculate the area of the square
Area = 6 x 6 = 36 u²
2.- Calculate the area of the rhombus
-Calculate the length of the short diagonal
6² = x² + x²
6² = 2x²
36 = 2x²
18 = x²
x = √18
-Short diagonal
x = 2√18
-Calculate the length of the long diagonal
10² = (√18)² + b²
b² = 100 - 18
b² = 82
b = √82
-Length of the long diagonal
d = √82 + √18
-Area of the rhombus
Area = (√82 + √18)(2√18) / 2
Area = (√82 + √18)(√18)
3.- Calculate the total area
Total area = (√82 + √18)(√18) + 36
-Simplification
Total area = (13.298)(4.243) + 36
Total area = 56.418 + 36
Total area = 92.4 cm²
120 even numbers that can be made out of those numbers.
