Step-by-step explanation:
If f(x)=6x+2,
f(x+3)=6(x+3)+2
f(x+3)=6x+18+2
f(x+3)=6x+20
Ok to start this problem you must list two numbers that add to 14
7 and 7
9 and 5
10 and 4
6 and 8
those are the numbers that we will use for now..
Now multiply each pair of numbers and see which one equals 45
7 * 7 = 49, no
9 * 5 = 45, YES
10 * 4 = 40, No
6 * 8 = 48, No
The numbers discovered are 9 and 5
The answer is 128 cause 8×4×4=128
