Answer:
y=(7)^x represents the exponential growth
Both numbers have the variable x so you add 5 and 12 which gives you 17 and you need to write the variable. The answer is 17x
Find a combination calculator, but in 14 and 4, choose combinations (not permutations) and you will see the number
Answer:
21
Step-by-step explanation:
3/(x-3) = 8/(2x+6)
or, 3(2x+6) = 8(x-3) ( by cross multiplication)
or, 6x + 18 = 8x - 24
or, 8x - 6x = 24 + 18
or, 2x = 42
or, x = 42/2
=21
