Answer
Perimeter = 1.75 times larger
Area = 3.0625 times larger
Step-by-step explanation:
Let the original quadrilateral have sides of a, b, c, d
Perimeter of the New Photograph
- Then the perimeter of the original is P = (a + b + c + d)
- Now the perimeter of the new quad is P = 1.75a + 1.75b + 1.75c + 1.75d
- Using the distributive Property we get P = 1.75(a + b + c + d) So the new perimeter is 1.75*the old perimeter.
Area of the New Photograph
The area is a little harder. Suppose the Old figure had an Area found by the formula of
- Area = e * f Each measurement is increased by a factor of 1.75
- Area_new = 1.75e * 1.75f
- Area_new = 3.0625 * e * f
- Area_new = 3.0625 * old area

= (y2-y1)/(x2-x1)
= (-9-(-5))(-2-(-4))
= (-4)(2)
= -8
Answer:
Step-by-step explanation:
Let x represent the number if months it will take for the total costs of both plans to be the same.
The first plan has $50 signup fee and costs $20 per month. This means that the total cost of using the first plan in a month would be
20x + 50
The second plan has $30 sign up fee and cost $25 per month. This means that the total cost of using the first plan in a month would be
25x + 30
For the costs to be the same,
20x + 50 = 25x + 30
25x - 20x = 50 - 30
5x = 20
x = 20/5 = 4
The costs would be the sane after 4 months. The cost would be
20 × 4 + 50
= $130
