1.  x^2+5x+6 = (x+3)(x+2), which implies that the sides could be x+3 and x+2.  (There are theoretically an infinite number of side-lengths, though--in general, for any polynomial or reciprocal of a polynomial P(x), \frac{x+3}{P(x)} and P(x)(x+2) is valid.  However, the set provided makes the most sense.)

2.  Profit is the difference between cost and revenue.  For revenue, 0.0000x^2 = 0, so revenue equals 40x, so profit equals 26x-120,000.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Shawn is collecting money from students at his school for a charity.

The table gives the ratios of the number of students who have donated and the amount of money he has collected from them.

Since 30 is 1/3 of 90, we know the ratio is 1:3.

In order of blank boxes going from left to right then down

1, 9, 5, 75, 35

The complete table is attached below.

A mule dear can 1/4 of a mile in 25 seconds. At this rate, what expression can be used to determine how fast a mule deer runs in
Naddika [18.5K]
We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144
Now, we can multiply 144 by 14 or .25 since we are trying to find per hour.
144×.25= 36
36h
H being the hours you're trying to find. It runs 36 miles per hour.
