First you need to move that n over im fairly certain
Answer:
1. Write the addition of "a", "b" and "c".
2. The equation is: 
Step-by-step explanation:
You know that <em>P</em> represents the perimeter of the triangle and <em>a, b </em>and <em>c </em>represent the sides of the triangle.
By definition, the sum is the result of an addition. Therefore, the statement "The perimeter <em>P</em> of a triangle is equal to the sum of the lengths of sides <em>a, b</em>, and <em>c</em>”, indicates that the perimeter is obtained by adding the lengths of the sides of the triangle.
Knowing this, you can write the following equation:

Answer:
x = 18
Step-by-step explanation:
total money = money spent + money left
x = 7+11
x = 18
Answer:
Step 1: Multiply 1x5 Step 2: Multiply 2x3 Step 3: Add the two products
d=v*t
d=distance
v=velocity(speed)
t=time
distance is equal to the product of velocity and time, equation form;
d=vt
