Suppose they decide to put fencing around both gardens,but not between the gardens.if b=10 how much fencing will they need? justify your answer. answer asap

B + b + b + b + b + 2b = 7b (add all the variables up )
7 x 10 = 70 ( since b = 10 substitute)

I assume that the equation is supposedly written as, y = (76)(1.013^x). This means that the population of the United States increases by 1.3% every year. If we substitute 0 to the value of x,
                                    y = 76(1.013^0) = 76(1) = 76
I assume that the unit for  y in the equation is million. Therefore, the answer is letter B. 76 million.
