Answer:
a(5)=25
a2+a6=44
a(4)+2a(6)=93
sqrta(5)=5
Step-by-step explanation:
You are given all the terms needed but sometimes you will have to create a formula.
a(b)=6b-5 is the formula in this sequence, now you can just plug in everything.
a(5)=6(5)-5
=25
a2=7
a6=37
7+37=44
a(4)=19, a(6)=37
19+2(37)=93
a(5)=25
sqrt25=5
The missing coefficient of n in n + 8 is 9 after adding like terms which is 2n and 7n.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have an expression:
= 2n + (7n + 8)
After adding like terms:
9n + 8
The coefficient of n in n + 8 is 9
Thus, the coefficient of n in n + 8 is 9 after adding like terms which is 2n and 7n.
