Answer: c=a2+b2
Step-by-step explanation: the triangle is solvedlike that
Answer:
Proportion states that the two fractions or ratios are equal
Given the equation: 
By cross multiply we get;

Using distributive property; 

Subtract 0.4 from both sides we get;

Subtract 1.5x from both sides we get;

Divide both sides by 0.1 we get;

Simplify:
x = 56
Therefore, the value of x that satisfy the equation
is, 56
First, combine 20c and 10c because they are like terms then combine 8d and -5d.
It would look like this:
20c+8d+10c-5d
30c+3d
