Define the length and the width of the rectangle
length = 5x + 4
width = 3x + 2

Determine the area
area = length × width
area = (5x + 4) (3x + 2)
area = (5x)(3x) + 2(5x) + 4(3x) + (4)(2)
area = 15x² + 10x + 12x + 8
area = 15x² + 22x + 8

The area of the rectangle is (15x² + 22x + 8) units²

15x^2 + 12x +10x + 8= 0 reduced 15x^2 +22x+ 8 = 0

15,000 blue trout were released into the Meherrin River for a scientific study. The function, f(x) = 15,000 (9/8)^x represents t

Ainat [17]

I'm guessing you mean f(x)=15,000(9/8)^x. If this is what you mean, the population would increase by about 12,000 (12030.4870605 to be exact).
Step-by-step explanation:
Starting equation: f(x)=15,000(9/8)^x
You can clean up the 9/8 to be 1.125
Now what you want to do is find the answer to (9/8)^5 which is 1.8020324707
Next multiply 1.8020324707 by 15,000 and you get 27030.4870605
Finally 27,030.4870605 - 15,000 gives you 12030.4870605. Which means that the population increased by about 12,000.
