If s(x) = x - 7 and t(x) = 4x7 - x+3, which expression is equivalent to (tºs)(x)?
4(x - 72 - x - 7+3
4(x - 72 -(x-7) + 3
(4x²-x+3)-7
(4x? – x+3)(x-7)

Step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
