Answer:

$a=9, b=26, c=24$

Step-by-step explanation:

Let's expand the expression bit by bit.

$(x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6$ by FOIL.

We have that $(x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24$ .

So, the answer is $\boxed{a=9, b=26, c=24}$

Write the first five terms of a sequence. Don’t make your sequence too simple. Write both an explicit formula and a recursive fo

Valentin [98]

Answer: The answer is 5, 10, 20, 40 and 80.

Step-by-step explanation: We are to write the first five terms of a sequence, along with the explicit and recursive formula for the general term of the sequence.

Let the first five terms of a sequence be 5, 10, 20, 40 and 80. These terms are taken from a geometric sequence with first term $a_1 5$ and common ratio $r=2.$
