Answer:
Step-by-step explanation:
C
Minus 1 both sides
x²-8x=-1
take 1/2 of the linear coefient and square it
-8 is the linear coefient
-8/2=-4, (-4)²=16
add 16 to both sides
x²-8x+16=16-1
factor perfect squaer trinomial
(x-4)²=15
square root both sides, remember to take positive and negative roots
x-4=+/-√15
not exactly sure what to put in the blnaks
but
the solutions are x=4+√15 and x=4-√15
The answers checked for #1, #2, #4, and #5 are correct.
In #3, the constant factor is -3 . So the absolute value of
each term is 3 times the absolute value of the previous one,
AND the signs alternate.
Ok i know that 6x divided by 42 would be 6 so were left with y=3. Do you know what the next step is?
Must show fractional dimensions!
