The sign of f on the interval -7/3 < x < -3/5 is always positive.
<h3>How to solve for the sign on the interval</h3>
We have the equation
(5x+3)(x−2)(3x+7)(x+5) > 0
Now when f(x) > 0
Then -7/3 < x < -3/5
This would tell us that the sign would become positive when it changes from the less than to greater than sign
<h3>Complete Question</h3>
f(x)=(5x+3)(x-2)(3x+7)(x+5) has zeros at x=-5, x=-7/3, x=-3/5, and x=2
What is the sign of f on the interval -7/3<x<-3/5?
answer choices
f is always positive on the interval
f is always negative on the interval
f is sometimes positive and sometimes negative on the interval
f is never positive or negative on the interval

> How many stamps did Mark have at first?
We know that Lisa has 1750 stamps and Mark has 480 fewer
than this, therefore subtract 480 from 1750 to get the number of stamps that
Mark had at first:
1750 – 480 = 1270 stamps
> How many stamps does Lisa have now?
Let us say that x = the number of stamps that Lisa gave
to Mark, therefore we can create the equation:
Mark = 3 * Lisa
480 + x = 3 (1750 – x)
480 + x = 5250 – 3x
4x = 4770
x = 1,192.50 stamps
So Lisa has now left with:
1750 – 1192.50 = 557.5 stamps ~ 557 stamps or 558
2,380 m^
Ratio of the sides 14/36 = 7/18
Ratio of the area is the ratio of the sides squared (7/8)^=49/324
49/324 = 360/A
A= 360*324 divided by 49 = 2,380.4081
