Answer:
Tiana sold 15 boxes and Jeremy and Keanu sold 10
Step-by-step explanation:
60% of 25 = 15
25 - 15 is 10
This is the way I understand the problem.
Answer:
B. x > 3
Step-by-step explanation:
Well we first simplify the following inequality,
3(8 - 4x) < 6(x - 5)
Distribute
24 - 12x < 6x - 30
Communicative property
-6x
24 - 18x < -30
-24
-18x < -54
Divide -18x by both sides
Which flips the < to a >.
x > 3
<em>Thus,</em>
<em>the answer is B. x > 3.</em>

Answer:
x=2 is not a solution
Step-by-step explanation:
x^4 +2x^3 -x^2 -2x = 0
I will factor by grouping
x^4 -x^2 + 2x^3 -2x =0
Factor out x^2 from the first group and 2x from the second group
x^2(x^2-1) +2x(x^2-1) =0
Now factor out x^2-1
(x^2-1) (x^2+2x)=0
From the second term we can factor out an x
(x^2-1) x(x+2)=0
Using the zero product property
(x^2-1) =0 x = 0 (x+2)=0
x^2 =1 x=0 x=-2
Taking the square root
x=±1 x=0 x= -2
The solutions are -2,-1,0,1
