Suppose we have a generic equation of the form:
1) The first thing you must do to complete squares is to group similar terms of the form:
2) The second step is to complete the squares.
3) The third step is factor the quadratic equation
4) The fourth step is to identify the center and the radius
Answer:
the first step in finding the center of the circle by completing the square is:
C group like terms
72° is the measure of both angles because 144/2= 72°
Answer: 13= 3.75
Step-by-step explanation: \
−4.5=−1.2k
Divide both sides by −1.2.
−1.2
−4.5
=k
Expand
−1.2
−4.5
by multiplying both numerator and the denominator by 10.
−12
−45
=k
Reduce the fraction
−12
−45
to lowest terms by extracting and canceling out −3.
4
15
=k
Swap sides so that all variable terms are on the left hand side.
k=

The answer is 71 since you count from the tenth space. So the first significant figure would be 7 and the second significant figure would be 0. As we know that we round up one number of the previous number is 5 or bigger.
