Answer:
Area = 2025 miles²
Perimeter = 180 miles
Step-by-step explanation:
Given the following :
Scale of drawing = 1 inch : 5 miles
Length of side of the scale drawing = 9 inches
To find The actual perimeter and area of the square, we need ;
Actual length of the drawing :
1 inch = 5 miles
9 inches = (5 × 9) miles = 45 miles
Hence,
Area of a square = a²
Where a = side length
Actual side length = 45 miles
Actual area of square = 45² = 2025 miles²
Actual Perimeter of square :
Perimeter of a square = 4a
a = side length
Actual perimeter = 4(45) = 180 miles
Answer:
The answer to your question is the letter D. (step 2)
Step-by-step explanation:
Data
P (7, 4) slope = 6
Process
1.- Write the equation of the line
y - y1 = m(x - x1)
x1 = 7 y1 = 4
2.- Substitution
y - 4 = 6(x - 7)
- Simplification
y - 4 = 6x - 42
- Solve for y
y = 6x - 42 + 4
y = 6x - 38 This is the equation in the point-slope form
3.- According to the choices the answer is letter D.
Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
