Answer:8^4 + 14^36 is the perimeter because they are for sides in a rectangle so you have to double the amount.
Answer:
<em>7, 22</em>
Step-by-step explanation:
Let S = the smaller number.
"The larger number is 1 more than 3 times the smaller number."
The larger number is 3S + 1.
The difference between the numbers is 15, so the larger number minus the smaller number equals 15.
3S + 1 - S = 15
2S + 1 = 15
2S = 14
S = 7
The smaller number is 7.
larger number = 3S + 1 = 3(7) + 1 = 21 + 1 = 22
The larger number is 22.
X - the number
3(x+1)=2x+4
3x+3=2x+4
3x-2x=4-3
x=1
