We are asked to solve for the zeros of the given quadratic equation f(x) = 9x2 + 6x + 1. To solve this, first, we need to set the given equation into zero such as the succeeding solution is shown below:
0 = 9x2 + 6x +1
Perform factoring such as:
0 = (3x + 1) (3x + 1)
Solving for x1, we have:
3x + 1=0
3x = -1
x1 = -1/3
Soving for x2, we have:
3x +1=0
x = -1/3
Therefore, the zeroes of the given expression is both -1/3 for x1 and x2.

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

(x-5)(x+1)<br> O x= -1 and x = 5<br> O x= -1 and x = 14<br> O x= 1 and x = -5<br> O x = 14 and x = 5
mafiozo [28]
Answer:

X= -1 and x=5

Explanation:

Make it equal to zero
X-5=0
Then add five to both sides
X=5
For the other one do the same
X+1=0
Then subtract one on both sides
X=-1

Hope this helps!
