The solutions to the given quadratic equation can be determined using quadratic formula.
b =coefficient of x term = -1
a = coefficient of squared term = 4
c = constant term = 9
Using the values in the above formula we get:
So, option D gives the correct answers
Answer: The Answer is
48 over 48+36
Step-by-step explanation:
Let me draw this triangle for you as you haven't drawn the triangle.
To find the side SR , you have shown that
ΔPST ~(is similar to)ΔPRQ [AA]
As, you know when triangles are similar their sides are proportional.
So,
You can solve this question using other way also
As, ST║RQ
then ⇒ [ if in a triangle a line is parallel to a side
intersecting the other two sides in distinct points then the ratio of the segments where the line segment intersects the other two sides are same.]
Solve using equations:
Gina 11 = a+b+c
Sam 27 = 2a+3b+2c
Robby 19= a+2b+2c
Gina *2 give 22=2a+2b+2c (subtract this from Sam to give)
b=5
the subtract Robby from Gina *2 to give a=3
[Question 1]
let d = number of dramas Gina rented, c = # of comedies, and t = # of documentaries:
[equation a] d + c + t = 11
[equation b] 2d + 3c + 2t = 27
[equation c] d + 2c + 2t = 19
if we subtract [a] from [c] we get:
[equation d] c + t = 8
if we subtract [c]*2 from [b] we get:
[equation e] -c - 2t = -11 or
[equation e] c + 2t = 11
Now we can subtract [e] from [d] to solve for t:
t = 3
Now put in 3 for t in [d] or [e] to solve for c:
c + 2(3) = 11
c + 6 = 11
c = 5
So she rented 5 comedies and 3 documentaries which leaves 3 dramas (which is answer A)
180 times 4/100= 7.20- Sales tax
180+7.20= $187.20 is the total cost

Answer:
11/238
Step-by-step explanation:
To find this, you must multiply the numerator by numerator (so in this case, -11 x -1; since you're multiplying a negative by a negative, they cancel out and it gives you a positive. So 11 x 1 is 11) Then, you multiply denominator by denominator. (14 and 17 is 238) So your fraction is 11/238. This can't be simplified any further.
