Since a is parallel to c and c is perpendicular to b, than a is also perpendicular to b.
perpendicular lines create right angles, so angle 1, 2, 3, 4, 5, 6 .7 & 8 are all right angles.
A right angle = 90 degrees.
Angle 2 = 90 degrees.
Think of it like this, what two numbers when multiplied together, you get 27, and when they add together, you get 12? The answer is 9 and 3,
Your answer here would be (r+9)(r+3) when factored.
ANSWER
After 7 years the car will worth, 7,759.5
EXPLANATION
The initial value of the car is 37000.
The rate of depreciation is 20%
In 7 years time, we can calculate the value of the car using the formula,
We substitute the values into the formula to obtain,
to the nearest tenth
Answer:
Example: 5(3x + 8)
