1. determine if the two expressions are equivalent and explain your reasoning. 8m + 4 - 3m and 3 + m + 2m + 1 + 2m 2.determine if the two expressions are equivalent and explain your reasoning. 9a + 12 and 3(3a + 4) 3.determine if the two expressions are equivalent and explain your reasoning. 3(4n) + 2 + 6n and 13n + 2 4.determine if the two expressions are equivalent and explain your reasoning. 11p + 2(p + 3) and 1 + p(13) + 2 you sooo much!

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

Anumber cube is rolled two times in a row. find the probability it will land on 2 on the first roll and a number greater then 4 on the second roll

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
