Step-by-step explanation:
First image attached
The error was done in Step E, because student did not multiply by the negative sign in numerator. The real numerator in Step E should be:
Hence, Step E must be .
Second image attached
The error was done in Step C, because the student omitted the of the algebraic identity . Step C must be

Answer:
Let's simplify step-by-step.
(−a)(−4 − 5a) − 3a(2 + a)
Distribute:
= (−a)(−4) + (−a)(−5a) + −3a^2 + −6a
= 4a + 5a^2 + −3a^2 + −6a
Combine Like Terms:
= 4a+5a^2 + −3a^2+ −6a
= (5a2+ −3a^2) + (4a + −6a)
= 2a2 + −2a
Final Answer:
= 2a^2−2a!
Answer:
Step-by-step explanation:
a1=7
a2=13
c.d. d=13-7=6
an=a1+(n-1)d
an=7+(n-1)6=7+6n-6=6n-1
recursive formula
c.d .=an-a(n-1)
6=a_{n}-a_{n-1}
a_{n}=a_{n-1}+6
