I am sure u have to separate the number with their variables so (4x) (2y -y ) (40+10)
Remember that you have to remove the brackets and u should have 4x - 1y + 50 then 4\4 and 50/4 = four cancles out 4 so we have 1y + 12.5 divide each by one one cancles out 1 = 12.5 round it up to 13 but I suggest u check this with anyone else you can but if my math is correct it should be the closest answer

Nicholas sent a chain letter to his friends, asking them to forward the letter to more friends. Every 12 weeks, the number of pe

Answer:

$P(t)=50(1.99)^{t/12}$

Step-by-step explanation:

The problem can be modeled by using the compound growth formula.

Given, Initial number P_0 of people who Nicholas sent the chain letter t=50

The growth rate, r =99%=0.99

Period of Growth,k =12 Weeks

$P(t)=P_0(1+r)^{t/k}$

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

$P(t)=50(1+0.99)^{t/12}\\\\P(t)=50(1.99)^{t/12}$

-3(6a+4) when a = -2

guajiro [1.7K]

Substitute the value of a = -2 to the expression -3(6a + 4):

-3(6 · (-2) + 4) = -3 · (-12 + 4) = -3 · (-8) = 24
