Answer:
the answer is -5< x
Step-by-step explanation:
you you start by subtracting 7 by both sides leaving you with -20<4x. then then divide both sides by 4 leaving you with -5< x
If x²-1 is a factor of the polynomial, both x-1 and x+1 are factors of it.
According to the remainder theorem, if a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
If x-1 and x+1 are factors of the polynomial p(x)=ax⁴+bx³+cx²+dx+e, then p(1)=0 and p(-1)=0.
Perpendicular: -4
Parallel: 1/4
There are 25 students in relay race and there are 5 equal teams, to find the number of team in relay, we can use division:
25÷5
=5
Therefore, a team have 5 sudent.
Hope it helps!
