Cloud [144]

Answer: The first option.


Step-by-step explanation:

1. The formula for calculate the perimeter is:

P=2l+2w

Where l is the lenght and w is the width.

2. The first perimeter is:

P_1=2(105m)+2(12.5m)=235m

3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:

P_2=2(2l+2w)

Where 2l+2w is the first perimeter.

4. Then:

 P_2=2(235m)=470m

A line passes through the point (4,-4) and has a slope of 5/4.
tester [92]

Answer:

y = 5/4x - 9

Step-by-step explanation:

y = mx + b

when you plot 4, -4 you have your first clue and point. then go up 5 and right 4 or down5 and left 4. When you go down you will reach the y intercept. On the number- 9. So -9 is your y intercept which goes in b.

Since 5/4 goes in the mx since it is slope the answer is y = 5/4 - 9
