Answer:
Step-by-step explanation:
To solve using completing square, we need to write the equation as x2+3x=17.
The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4
The equation then becomes x2+3x+(9/4)=17+(9/4).
Solving it further will get you the final answer
Answer:
C. 55 inches
Step-by-step explanation:
a^2 = b^2 + c^2
a^2 = 47.5^2 + 27^2
a^2 = 2985.25
a = 54.637 = 55 inches
The Constant Of Proportionality is 45.2
