Answer: 60 ft
Separate into 2 rectangles and add their areas together!
Vertical rectangle area: 10 x 3 = 30 ft
Horizontal rectangle area: 10 x 3 = 30 ft
Area of entire thing: 30 + 30 = 60 ft

You just subtract 3 from each side and then simplify (12 - 3) which is 9.
The final result is:
x ≥ 9.
The distance formula is given by

Take point A(0, -7) as (x₁, x₂) and point B(8, 8) as (y₁, y₂)
Distance AB =

Distance AB =

Distance AB =

Distance AB = 17
The line AB is dilated to A'B' by scale factor of 2, it means the length of the line is multiplied by 2
Distance A'B' = 2 × 17 = 34 units
The required equation is y = -9
Step-by-step explanation:
Step 1 :
Given the line l is perpendicular to the y axis
The equation of the y axis is x = 0
So any line perpendicular to the y axis will have equation as y = k , where k is a constant value for any value of x
Step 2 :
Its given that the line is passing through the point (0.-9). Here the y co ordinate is -9. Hence the perpendicular line has a constant y co ordinate of y = -9 for any value of x
So the required equation is y = -9
Step 3 :
Answer :
The required equation is y = -9
