Answer:
B. 3.6 x 10^3
Step-by-step explanation:
(1.2 x 10^-2) x (3 x 10^5)
When we multiply terms with powers , we multiply the factors out front and add the exponents
a * 10^b * c* 10^d = ac * 10^(b+d)
(1.2 x 10^-2) x (3 x 10^5) = (1.2* 3) * 10^(-2+5)
= 3.6 * 10 ^3

Answer:
w = 80/9 ft.
L = 640/9 ft.
Step-by-step explanation:
L = length w = width
2w = L/4 so 8w = L

160 = 18w
80/9 = w
