Answer:
42
Step-by-step explanation:
3(x+x+6)=270
3(2x+6)=270
6x+18=270
6x=252
x=42
Answer:
u can say me
Step-by-step explanation:
9 hrs and 18 minutes = 8 hrs and 78 minutes......all I did was borrow 1 hr from the hr side, convert it to 60 minutes, and add that to the minute side.
8 hrs 78 minutes
2 hrs 55 minutes
-------------------------subtract
6 hrs 23 minutes <=== ur answer
Answer:
No. We can conclude that (x-4) is <u>not</u> a factor of the polynomial.
Step-by-step explanation:
The <em>polynomial remainder theorem</em> tells you (x-4) will be a factor of the polynomial f(x) if and only if f(4) = 0. When we evaluate ...
f(x) = 4x³ -20x² +18x -12
at x=4, we find that f(4) = -4. This is not zero, so (x-4) is not a factor of f(x).
_____
The evaluation is perhaps easiest done by hand when the function is written in Horner form:
f(x) = ((4x -20)x +18)x -12
f(4) = ((4·4 -10)4 +18)4 -12 = ((-4)4 +18)4 -12 = 2·4 -12
f(4) = -4
_____
The one real factor of this polynomial is irrational, and the remaining factors are complex and irrational.
Step-by-step explanation:
focus=(0,4)
Direcrtrix,y=-4
p=4
vertex=(0,0)
Open upward
(x-h)²=4p(y-k)
(x-0)²=4(4)(y-0)
(x-0)²=16(y-0)
