Answer:

20

Step-by-step explanation:

Evaluate by substituting n = 3 into the expression

9 + (4 × 3) - 1 ← evaluate the multiplication before adding/ subtracting

= 9 + 12 - 1

= 21 - 1

= 20

First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20

so your answer would be 20

HELP ASAP!!! WILL GIVE BRAINLEIST!!!
netineya [11]

Answer:

The first question is (n*8) - 4

The second question is no.

Step-by-step explanation:

The first question, you add 8. The first is 1. 1 * 8 = 8 - 4 = 4.

Therefore, the equation is (n*8) - 4

The second question, you can plug in numbers. You can solve for a term.  -100 + 17 = -83. -83 is not a multiple of -4. -100 is not a term.

Brian says that the expression 8n + 2 is equal to 83 when n=1. Explain why Brian’s answer is incorrect?
GalinKa [24]

Answer:

8n+2 first let’s plug in n which is 1

8(1)+2=10

The answer is 10 but Brian said the expression is equal to 83. He is incorrect because 8 times 1 is 8 and then plus 2 is 10.

I hope it helps.
