Answer: no; A 1 X 5 rectangle has a perimeter of 12 units and does not have an area of 6 units, so a counterexample shows that your friends statement is not correct
85 = 80 + 5
85 = 8*10 + 5*1
85 = 8*10^1 + 5*10^0
Answer:
Hello,
Step-by-step explanation:
a(1) = -4(1)-3 = -4-3 = -7
a(2) = -4(2)-3 = -8-3 = -11
a(3) = -4(3)-3 = -12-3 = -15
a(4) = -4(4)-3 = -16-3 = -19
a(5) = -4(5)-3 = -20-3 = -23
So, sequence would be -7,-11,-15,-19,-23
Answer: X=3
The sum and difference of 5 and 19 is 3
