The i you normally think of (the one = to sqrt(-1) is not the same i they are using here. They are using this i the same way you would use x = - 1 in any normal equation or relation.
1a + b(-1)
a - b is your answer <<<< answer
The answer is 0.5 when the second decimal is 5 or more you round to the next number
Step-by-step explanation:
Solve the first eqn for b, b=13–2*a, and the 2nd for c, c=(6*a+5)/3. Then
b+c=13–2*a+(6*a+5)/3=13–2*a+2*a+5/3=44/3. We see that b+c has a definite value because the terms in a cancel.
7.2x10^-3--->.0072
you take 7.2 and move the decimal point 3 places to the left
Answer:
The (minimum) number of toothpicks required to make an acute angle scalene triangle is 3.
