Answer:

Step-by-step explanation:
From C-A, it goes from y=1 to y=5, so that 4 units
From A-B, it goes from x = -1 to x = 4, that is 5 units
Now, to find distance from B to C, we need to use the distance formula:

Where the variables are the respective points of B and C,
B (4,5) & C(-1,1)
So x_1 =4, y_1=5, x_2=-1, y_2=1
Plugging into the formula we get:

Summing it all (perimeter is sum of 3 sides):
Distance = 
3rd answer choice is right.
Scale = 88 feet/5.5 inch = 16ft/inch or 16 feet = 1 inch Width = 76 feet x 1 inch/16 feet = 4.75 inches.
Answer:
Step-by-step explanation:
the answer to number 7 is 1953152
Answer:
21 cm
Step-by-step explanation:
Since this is an isosceles triangle, the two sides with a line through them must have the same value of x. Therefore, you can set up the following equation:
2x+11=53
2x=42
x=21 cm
Hope this helps!
Distance is the formula :
D

=
so

= 13
