Answer: d=7.5
Step-by-step explanation: 5.5=−2+d d−2+2=5.5+2 d=7.5
By the binomial theorem,

I assume you meant to say "independent", not "indecent", meaning we're looking for the constant term in the expansion. This happens for k such that
12 - 3k = 0 ===> 3k = 12 ===> k = 4
which corresponds to the constant coefficient

Answer:
1.50
Step-by-step explanation:
8 x 1.50=12
25-12=13
13-4=9
9/6=1.5
The answer is B. 2y+3
this is proven by multiplying the divisor of the original question and the solution
5(0.85)t < 1.5 is 15% decay
50(1.05)t < 100 is 5% growth
150(1.50)t > 500 is 50% growth
50(1.15)t < 150 is 15% growth
