Just replace a with 4 and b with 2 and your equation looks like
3.14 (4×2+4×2)
solve within the parenthesis first
3.14 (8+8)
3.14 (16) =50.24
It should be a 10% tip. To simplify the answer, The decimal moves one space (which would be equal to a tenth) so it’s a 10%
-8, -19, -30, -49 , -60
<u>Step-by-step explanation:</u>
Here we have the following sequence :
-8, -19, -30, _ , _
- First term of sequence is -8 .
- Second term of sequence is -19 :

- Third term of sequence is -30 :

- Fourth term of sequence is :

- Fifth term of sequence is :
Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e.
and common difference
having general equation as :
.
