Answer:
A *am + am = ab
because of substitution, above it says that am = mb
so you substitute
Since quadratic coefient is 1 (term in front of x^2)
take 1/2 of linear cofient (12) and square it
12/2=6, 6^2=36
add that to both sides
x^2+12x+36=-11+36
factor perfect square
(x+6)^2=25
sqrt both sides and take positiv and negative roots
x+6=+/-5
minus 6 both sides
x=-6+/-5
x=-6+5 or x=-6-5
x=-1 or -11
answer is {-11,-1}

Answer:
The correct graph is the first graph on the top left corner amongst the options
Step-by-step explanation:
The graph that shows that Cindy reads about 3/4 of the time while riding the car is given by the following relation;
Let 't' represent the time Cindy spend riding the car
Therefore, we are given that
The time Cindy spend reading = 3/4·t
Therefore, when Cindy rides the car for t = 4 hours, the time Cindy spend reading = 3/4·t = 3/4 × 4 = 3 hours
The coordinates of the point on the graph will therefore, be (4, 3)
Therefore, when the y-coordinate of the graph )the time Cindy spends reading) = 3, the x-coordinate of the graph (the time Cindy spends driving) = 4
