<span>The cubic factors- (x - 3)(x² - 2) = 0.</span>
Answer:
Step-by-step explanation:
A function is given to us and we need to find the x Intercepts of the graph of the given function . The function is ,
For finding the x intercept , <u>equate the given function with 0, we have ;</u>
Equate each factor with 0 ,
Divide both sides by 2 ,
Again ,
Taking squareroot on both sides,
Add 5 to both sides,
Similarly ,
<u>Hence</u><u> the</u><u> </u><u>x </u><u>Intercepts</u><u> </u><u>are </u><u>-</u><u>4</u><u> </u><u>,</u><u> </u><u>0</u><u> </u><u>and </u><u>5</u><u> </u><u>.</u>

Total = 21 feet
if each is 3 feet
21/3 = 7
Therefore, there are 7 sections
Answer:
<h3>The ratio of technicians to all helpers is 11 : 7, or

or 11 to 7.</h3>
Step-by-step explanation:
- Given that there are 7 ushers and 11 technicians helping at the Harper Middle School fall play.
- Let x be the number of ushers ( or helpers ).
- Therefore x=7 helpers.
- Let y be the number of technicians.
- Therefore y=11 technicians.
<h3>To find the ratio of technicians to all helpers :</h3>
That is to find the ratio of y to x.
We can write the ratio of technicians to all ushers(helpers) as y : x
Which implies that 11 : 7, (since y=11 and x=7)
Or
or 11 to 7
<h3>The ratio of technicians to all helpers is 11 : 7, or

or 11 to 7</h3>
Answer:
x = 9
Step-by-step explanation:
subtract 5 from 11 with = 6
divide by -2 which = -3
square your answer so (-3)² = 9
