Answer:
Isn't it 18?
Step-by-step explanation:
Because you need to add 4 and 2 then multiply it with 3?
The rate of change of the linear equation is 
Explanation:
The given two coordinates are
and 
To determine the rate of change, let us use the formula,

Substituting the coordinates in the equation, we get,

Simplifying, we have,

Dividing, we get,

Thus, the rate of change of the linear equation is 
Step-by-step explanation:
Y=90° as its a right angled triangle
Answer:3,600
Step-by-step explanation:
Find the Prime factorization of 400: 2x2x2x2x5x5
Find the Prime factorization of 900: 2x2x3x3x5x5
Multiply each factor the greater number of times it occurs: 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5= 3,600
