Answer:
Step-by-step explanation:
The first step is to realize that this is a geometric sequence, where each next term in the sequence is 2.5 times larger than the previous. You can confirm this by the fact that 3=1.2*2.5, 7.5=3*2.5, and 18.75=7.5*2.5. Now, you can write the formula, where n is where the number is in the sequence, and a is the number itself. Since 1.2 is the first term in the sequence and the rate of expansion is 2.5, the formula is:

Answer:
width=11/2
length=8
Step-by-step explanation:
44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>
44=2w^2 - 3w <em>distribute</em>
2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>
(w+4)(2w-11) <em>factor</em>
width=11/2
(11/2 x 2) - 3
length = 8
Y= 8x would be the equation as in mx+b, mx equals the slope (8/1 = 8) and b equals the y intercept which is 0.
You could subtract the denominator fro the numerator which would give you a total sum of 1 thousand an fifty five
