Answer:
2x^2-5x-12
Step-by-step explanation:
a rectangle has a length of 2x+3 and a width of x-4 find the area
------------
Area = length * width
-------------------------
A = (2x+3)(x-4)
---
A = 2x(x-4)+3(x-4)
---
A = 2x^2-8x+3x-12
---
A = 2x^2-5x-12

Answer:
about 520,000
Step-by-step explanation:
Following directions, we evaluate the equation by putting the value where the variable is and doing the arithmetic.
__
The value of x will be the number of days between May 26 and May 12. That value is ...
x = 26 -12 = 14
Then the number of mosquitos is estimated to be ...
y = 230,000(1.06^14) ≈ 520,008
About 520,000 mosquitos will inhabit the city on May 26.
_____
<em>Additional comment</em>
Typically, an "estimate" is one or two significant figures. So, 520,000 is a reasonable estimate. 520,008 has more precsision than can be justified.
