x + 4 is prime x2 – 9 can be factored using the formula.
We are given two binomials: x+4 , x^2-9.
x+4 can't be factored. Therefore, it is a prime.
Let us work on x^2-9.
9 could be written as 3^2.
Therefore, x^2-9 = x^2 - 3^2.
Now, we can apply difference of the squares formula to factor it.
We know a^2 -b^2 = (a-b) (a+b).
Therefore, x^2 - 3^2 can be factored as (x-3) (x+3).
So, x^2-9 is not a prime binomial because it can be factored as (x-3) (x+3).
Answer:
difference-of-squares
Step-by-step explanation:
x + 4 is prime
x2 – 9 can be factored using the
difference-of-squares formula.

Substitute y = 2x - 15 to the second equation:
4x + 3(2x - 15) = -5 use distributive property
4x + (3)(2x) + (3)(-15) = -5
4x + 6x - 45 = -5 add 45 to both sides
10x = 40 divide both sides by 10
x = 4
Substitute the value of x to the equation y = 2x - 15:
y = 2(4) - 15 = 8 - 15 = -7

3-6+5 is equal to 2, as opposed to 3-5+6 which is 4. The commutative property is only applicable to positive numbers, in this case, Jerome could have done 5-6+3, which would still equal to 2.
The sign is part of the number.
The first term is +3, the second term is -6, and the third term is +5
In order to use the commutative property so that the -6 and +5 are switched, it would be rewritten as: 3 + 5 - 6
Answer: Jerome did not include the sign with the number when he used the commutative property.

Man's height, m = 6 feetsMan's shadow, s = 3.5 feets Building shadow, b = 14.875 feets Building height , h =?Setting up a proportional relationship :
Man's height / shadow = Building height / shadow
6 / 3.5 = h / 14.875
Cross multiply :
3.5h = 14.875 × 6
3.5h = 89.25
Divide both sides by 3.5 to isolate h
h = 89.25 / 3.5
h = 25.50 feets
Therefore, the length of the building is 25.50 feets

At the supermarket you can fill your own honey bear container. A custoner buys 12 oz of honey for $ 5.40.
A. how much does honey cost per ounce?
B. how much honey can you buy per dollar?
C. write to different equations that represent this situation. use h for ounces of honey and c for cost in dollars.
D. Choose one of your equations and sketch its graph. be sure to label the axes. ((DUE TOMMAROW))
Total number of oz of honey = 12 oz.
Cost of 12 oz of honey = $5.40.
Cost per oz of honey = 5.40 divided 12 = $0.45 per oz.
Therefore,
a) Cost per ounce of honey = $0.45.
b) Number of ounces we can buy for one dollar = 12 divided by 5.40 = 2.22 oz approximatly.
c)
h = 2.22c, wherr h is the number of ounces of honey for c dollars.
c=0.45h, where c is the total cost of h number of ounces of honey.
d) Let us take c=0.45h equation for graph the situation.
x-axis would be for h number of ounces of honey and y-axis is the total cost c of h ounces of honey.
Let us find some values of h and c for the graph.
For equation: c=0.45h for h=1,we get c=$0.45.
If we plug h=2, we get c= 0.45*2 = $0.90.
If we plug h=3, we get c= 0.45*3 = $1.35.
Therefore, we would plot (1,0.45), (2,0.90) and (3,1.35) on the graph and draw a straight line.
The relationship between the honey bear and the rates is an illustration of a linear function.
The price of honey per ounce is $0.45$1 will buy you 2.22 ounce of honeyThe equations for this situation are [tex]\mathbf{h = 2.22c}[/tex] and [tex]\mathbf{c = 0.45h}[/tex](a) The unit price of honey
From the question, we have:
[tex]\mathbf{\$5.40 = 12oz}[/tex]
So, the unit rate is:
[tex]\mathbf{Unit = \frac{\$5.40}{ 12oz}}[/tex]
[tex]\mathbf{Unit = \$0.45\ per\ oz}[/tex]
The price of honey per ounce is $0.45
(b) Quantity of honey for $1
In (a), we have:
[tex]\mathbf{Unit = \$0.45\ per\ oz}[/tex]
Take the inverse
[tex]\mathbf{Qty = \frac{1}{0.45}}[/tex]
[tex]\mathbf{Qty = 2.22}[/tex]
$1 will buy you 2.22 ounce of honey
(c) Different equations
Let represents the cost of honey, and h represent the ounce
In (a), we have:
[tex]\mathbf{Unit = \$0.45\ per\ oz}[/tex]
As an equation, it becomes
[tex]\mathbf{c = 0.45h}[/tex]
In (b), we have:
[tex]\mathbf{Qty = 2.22}[/tex]
As an equation, it becomes
[tex]\mathbf{h = 2.22c}[/tex]
Hence, the equations for this situation are [tex]\mathbf{h = 2.22c}[/tex] and [tex]\mathbf{c = 0.45h}[/tex]

Answer:
Option B. 66 cookies
Step-by-step explanation:
The complete question is
Bella is baking chocolate chip cookies for an event. It takes 3/5 of a cup of flour to bake 6 cookies. She uses 1 1/10 cups of flour for every 50 chocolate chips used. There are a total of 150 chocolate chips for each tray of cookies. If Bella is baking 2 trays of chocolate chip cookies, then how many cookies will she bake in total?
step 1
we know that
There are a total of 150 chocolate chips for each tray of cookies
Find out the number of chocolate chips if Bella is baking 2 trays
so
using proportion
Let
x ----> the number of chocolate chips
[tex]\frac{150}{1}=\frac{x}{2}\\\\x=150(2)\\\\x=300\ chocolate\ chips[/tex]
step 2
we know that
She uses 1 1/10 cups of flour for every 50 chocolate chips used.
Find out the number of cups of flour for 300 chocolate chips
so
using proportion
Let
x ----> the number of cups of flour
Convert mixed number to an improper fraction
[tex]1\frac{1}{10}\ cups=\frac{1*10+1}{10}=\frac{11}{10}\ cups[/tex]
[tex]\frac{(\frac{11}{10})}{50}=\frac{x}{300}\\\\x=\frac{66}{10}\ cups[/tex]
Simplify
[tex]\frac{66}{10}\ cups=\frac{33}{5}\ cups[/tex]
step 3
we know that
It takes 3/5 of a cup of flour to bake 6 cookies
Find out the number of cookies she bake for 33/5 cups of flour
so
using proportion
Let
x -----> the number of cookies
[tex]\frac{6}{(3/5)}=\frac{x}{(33/5)}\\\\x=6(33)/3\\\\x=66\ cookies[/tex]

Answer:
not a valid study
Step-by-step explanation:
Given that
Kai is conducting a study about the percentage of students with jobs. His school has 2500 students. He asks everyone in his drama class to participate in a survey. He bases his findings on these results.
Just selecting only students in his drama class to form the sample will not give accurate results since samples are not drawn at random. The sample done is convenient sample saving time, but failing to represent the entire student population with jobs.
THe best sample would be group the students with jobs and select from the group at random a sample size proportional to the population size.
