Step-by-step explanation:
First, let's move the to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:
From here, since the coefficient of the term is , we know the square will be (since it's half of ).
To complete this square, we will need to add to both sides of the equation:
Now we can take the square root of both sides to figure out the solutions to :
Answer:
Step-by-step explanation:
(7*11)-(22/7*2^2)
77-(22/7*4)
77-88/7
77-12.57
64.43
452 because you will multiply 80 by 6 and get 480 and subtract 28 from that!
Answer:
QRT = 47, TRS = 133
Step-by-step explanation:
Since QRS is a line, QRT + TRS = 180.
Then, solve for x. Combine like terms.
Then, plug in 14 for x.
