Answer:
- 6(x^2 +18z +81) . . . as written
- 6(x +9)^2 . . . . . . . . assuming a typo
Step-by-step explanation:
As the expression is written, the only factoring that can be done is to factor out the common numeric factor of 6:
= 6(x^2 +18z +81)
__
<em>Assuming a typo in the question</em>
If we assume all variables are supposed to be "x", then the quadratic term can be further factored as a square:
= 6(x +9)^2
_____
It is often handy to remember that the form of the square of a binomial is ...
(a +b)^2 = a^2 +2ab +b^2
Here, we recognize that 18 = 2√81, so the binomial is (x +√81) = (x +9).
It is something that is not consistent. Having a fixed pattern or liable to be changed.
Answer:
N=-13
Step-by-step explanation:
Answer:
She will need 4 square and 8 triangular pieces.
Step-by-step explanation:
For every 6 pieces of cloth, 2 are squares.
So, for 12 pieces of cloth, the no. of square pieces would be,
= 
= 4
As the remaining pieces will be triangles, so the no. of triangular pieces will be, equal to,
(12 - 4) = 8
for every 1/10 second it travels 21.98 inches
for a full second it travels 21.98 x 10 = 219.8 inches
for 1 minute it travels 219.8 x 60 = 13188 inches / 12 = 1099 feet per minute
1099*60 = 65940 feet per hour
5280 feet per mile
65940/5280 = 12.488= 12.5 miles per hour
