Answer:
y = 5x+2 , y=x-6
Step-by-step explanation:
just by looking at the table you can see for the first one 5x + 2 satisfies the table, and x-6 satisfies the right table.
The simplified expression is
Explanation:
The expression is
Grouping the like terms,
Adding the like terms, we get,
Subtracting the values, we have,
Thus, the simplified expression is

Answer:
120 + 20π
Step-by-step explanation:
Find the image of the question attached.
For the square;
Perimeter of a square = 4L
L is the side length of the square
From the diagram, L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
For the semicircles:
Perimeter of a semicircle = 2πr/2 = πr
From the diagram;
L = radius of the semicircle = 10
Perimeter of a semicircle = π(10)
Perimeter of a semicircle = 10π
Perimeter of the two semicircles = 2(10π) = 20π
perimeter of the shape = perimeter of 3squares + 2 semicircles
perimeter of the shape = 120 + 20π
