Get into ax²+bx+c=0 form
subsitute u=x⁴
x⁸-3x⁴+2=0
(x⁴)²-3(x⁴)+2=0
u²-3u+2=0
factor
(u-2)(u-1)=0
set to zero
u-2=0
u=2
u-1=0
u=1
wait, u=x⁴
2=x⁴
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
1=x⁴
+/-1=x
the subsitution is u=x⁴
and the possible values for x are -1,
, and 1
Let a = weight of large box in pounds
Let b = weight of small box in pounds
(1) 65a + 70b=4000
(2) a+b=60
Now we can simultaneously solve these equations.
a = 60 - b. Hence 65(60 - b) + 70b = 4000 So 3900 + 5b = 4000 and 100 = 5b hence b = 20.
SImilarly a = 40. Now we can verify too by putting in the calculated values.
Answer:
Step-by-step explanation:
First, convert the 4 mins into hours by dividing by 60;
4/60 =0.067
Add 0.067 to 75 hrs to get the total = 75+0.067 = 75.067
Therefore the total time Chris needs to make up for is 75.067 hrs
Total number of days Chris has = 25
Next,
IF in 25 days = he can cover 75.067hrs
then in 1 day he will cover = (1 * 75.067)/ 25
= 3.002
Therefore, Chris needs to do 3hrs each day to be able to complete the deadline
