Answer:
13cm
Step-by-step explanation:
Let the length of each side be x;
Using the pythagoras theorem
l² = x² + x²
l is the length of the diagonal
l² = 2x²
19² = 2x²
361 = 2x²
x² = 361/2
x² = 180.5
x =√180.5
x = 13
hence the length of each side of the square is closest to 13cm

Answer:
a
Step-by-step explanation:
multiply the radius of 3 by 3 to get 9, and multiply the height of 4 to get 12. the radius of cylinder a = 9 and the height of a = 12 therefore if you fill cylinder b up 3 times you will fill up a.
Answer:
y- intercept = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
+ 
= 1
Multiply through by 6 to clear the fractions
2x + 3y = 6 ( subtract 2x from both sides )
3y = - 2x + 6 ( divide all terms by 3 )
y = - 
x + 2 ← in slope- intercept form
with y- intercept c = 2
