A triangular shaped stack of tin cans has 8 cans in the first row and 8 rows in all. In each successive row one can is removed.
Daniel [21]
If n is the number of cans in row r
n = 9 - r where r is a natural number less than 9

When r = 5 then n = 9 - 5 = 4

(you could let r = 9 as the ninth row has zero cans but values above 9 will give negative counts)

Vivian is solving the equation 0=x2−5x−4 0 = x 2 − 5 x − 4 using the quadratic formula. Which value is the negative real number
Aleks [24]
<h3><u>answer</u><u>:</u></h3>

-0.7

<h3><em><u>steps</u></em><em><u>:</u></em></h3>

the quadratic formula is

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

substitute the correct values in

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

where it says +- you would type this into your calculator with + AND THEN - to get two separate answers.

when you type + you get the answer of: 5.701562119...

when you type - you get the answer of:

-0.7015621187...

when you round to the nearest tenth you get -0.7
