Answer:

He set the factored expressions equal to each other. instead of setting them equal to zero

Step-by-step explanation:

f(x) = x^2 + 4x + 3. His work is shown below.

0 = x^2 + 4x + 3

0 = (x + 3)(x + 1)

Here is where we use the zero product property

x+3 = 0 x+1 =0 We do not set them equal to each other

The data for resort A shows more consistency because a larger interquartile range such as the one for resort B, shows more variation. This means that the snowfall for resort A is more likely to be close to the median.

Please Help Me Asap I Need Units Too

Hello and Good Morning/Afternoon

Let's take this problem step by step:

To find the rate of change is essentially like finding a line's slope:

⇒ the x-values are the number of sodas

⇒ the y-values are the total costs

⇒ choose two sets of coordinates and find the slope

Let's put that into action

Choose any two points

⇒ (24, 18)

⇒ (28, 21)

Calculate Slope

$Rate_.of_.change = \frac{21-18}{28-24} =\frac{3}{4}$

Since the rate of change is total cost over number of sodas

⇒ unit is 'total cost/number of sodas'

Answer: 3/4 total cost/number of sodas

Hope that helps!

Using the order of operations, what would be the first step: 4−8÷1−3[3+(7−5)2]

jeka94

Answer:

(7-5)

Step-by-step explanation:

According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.

Next would be [3+(2*2)]

Then, [3+4]

Then, -8/1

Then, -3(7)

So the question would be 4-8-21

Which gives you -25 as an answer.

I realize that you weren't asking for the whole thing but maybe there are follow up questions.
