Answer:
Just combine the x
Step-by-step explanation:
Hello
by identity : a²-b² = (a-b)(a+b)
m²-25 = m²-5² (m-5)(m+5)
Based on the task content; If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always. Option B
<h3>Multiplication of inequality</h3>
Based on the rule of inequality, whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.
For instance,
-4x > 12
divide both sides by -4
x < 12/-4
x < -3
If you multiply both sides of an inequality by a negative number, the inequality symbol should be reversed always.

Answer:
Use the formula Tn=a+(n-1)d

Tn= -1+(n-1)(4)
Tn=-1+4n-4
Tn=4n-5
