How many, and what type of solutions, does3x2−x−5=0 have?
siniylev [52]

Answer:

2 irrational solutions

Step-by-step explanation:

using the quadratic formula:

\frac{ -b \:± \sqrt{b {}^{2} - 4ac }   }{2a}

3x²−x−5=0

where a = 3, b = -1 and c = -5, plug in those values in the quadratic formula

\frac{ - ( - 1)±\sqrt{(1) {}^{2} - 4(3)( - 5) } }{2(3)}

you get two solutions:

\frac{1 +  \sqrt{61} }{6} \:  and \:  \frac{1 -  \sqrt{61} }{6}

both can be written as:

\frac{1± \sqrt{61} }{6}

They are irrational as they cannot be written in the form p/q where p and q are whole numbers (integers)

Jenn will use 18 connecting cubes to make a model of a park. The model will be in the shape of a rectangle and will have a heigh
Margarita [4]
This question is basically: how many different pairs of numbers multiply up to 18?

(This is a simpler form of the question because the question is just asking how many shapes of a rectangle can Jenn create with 18 blocks)

So, the numbers that multiply up to 18 are:

1 x 18
2 x 9
3 x 6

So, the answer is: Jenn can make the model of the park in 3 different ways.
