Katie has equation
and wants to solve it completing the perfect square. In order to do it, first rewrite 7 in right side:

Then note that
so Katie has to add
to both sides (because
):

Answer: correct choice is C.
Sorry really don’t know just make a guess
Answer:
A four mile ride would cost $10
Step-by-step explanation:
Let T be the total ride cost
Let M be the amount of miles driven
T = 1.75M + 3
You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles
T = 1.75*(4) + 3
T = 7 + 3
T = 10
Therefore, a four mile ride would cost 10 dollars
PT 1
the circumference of a circle is always pi times the diameter. The diameter is 2 times the radius, because diameter is all the way across the circle, whereas radius is from the center of the circle to the edge. Anyways, if the radius is 6, multiply it by 2 and you get 12, so 3.14 times 12 is 37.68, which is the answer.
PT 2
diameter=9 cm. So, just do 9 times 3.14. (diameter times pi = circumference.)
(2*radius times pi = circumference.)
9 times 3.14 is 28.26
