<span>factors of 30 are numbers by which 30 is divisible.
if we list out 30 as a product of factors 30 = 1 x 30
30 = 2 x 15
30 = 3 x 10
30 = 5 x 6
therefore all the factors of 30 are - 1,2,3,5,6,10,15,30
the numbers 3 and 6 add up to 9.
therefore the 2 factors that add up to 9 are 3 and 6</span>
Answer: x=38
Step-by-step explanation:
x+(-15)=23
x-15=23
+15 +15
x=38
When there is a positive and negative sign the negative sign cancels the positive sign.

Answer:
Part 1) Vertical line : 
Part 2) Horizontal line : 
Step-by-step explanation:
Part 1) Write the equation for the vertical line passing through the point (1,-4)
we know that
The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it
so
The x-coordinate is 1
therefore
The equation of the line is

Part 2) Write the equation for the horizontal line passing through the point (1,-4)
we know that
The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it
so
The y-coordinate is -4
therefore
The equation of the line is

Answer:
The area = 486 cm^2
The length is 54 cm and the width is 9 cm
54 times 9 = 486
