Every single one of those polynomials factors. When factored, your expression looks like this: 
. When you cancel the like factors out, what you're left with is this: 
. That means that b = 9, c = 1, and d = -2
Answer:
200 students attended the basketball game
Step-by-step explanation:
The complete question in the attached figure
Let
x ------> the number of students in fourth grade
s -----> the number of students at the basketball game
we know that
The number of students at the basketball game is four times the number of students in fourth grade
so
The linear expression is
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
therefore
200 students attended the basketball game
Remember that the area of a rectangle is length times width; since we don't know the width, we'll use the Pythagorean theorem to find it first:
Where l is the leg, and h the hypotenuse. We know that one of the legs, the base has a measures 34.3 inches and the hypotenuse a measures 42.1 inches.
Replace the values to get:
Now that we know the width (w), we just net to multiply it by the length to get our area:
We can conclude that the correct answer is <span>B) 836.9 in.</span>
