What does it mean to factor using the Greatest
Common Factor? Provide an example
Answer:
below ⬇
Step-by-step explanation:
when you factor out the greatest common factor, you take out number, variable, or term which is common in all of the monomials in the expression/equation.
an example is...
un-factored: 7x^2+14xy+21x
factored: 7x(x+2y+3)
that's all! hope this helped!!

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator
Answer:
This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".
Step-by-step explanation:
This is the Exact sample response,
Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.
A store owner wants to prepare 100 lb of a candy mix that she will sell for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?
Answer:
33/20
Step-by-step explanation
$0.2 + $x = %1.36
20 IB + 80 IB = 100 IB
Equation: 0.2*20+x*80=1.36*100
there fore the answer is 33/20
The cost of 1 lb of sugar candies is $1.65.
ExplanationGiven to us
weight of candy mix = 100 lb,weight of jelly beans = 100 lb,Cost of jelly beans = 20 cent per lb = $0.20 per lb,Cost of candy mix = $1.36 per lb.Total cost of candy mixTotal cost of candy mix = weight of candy mix [tex]\times[/tex] Cost of candy mix
[tex]= 100\ lb\times \$1.36[/tex]
Total cost of Jelly beans
Total cost of Jelly beans = weight of Jelly beans [tex]\times[/tex] Cost of Jelly beans
[tex]= 20\ lb\times \$0.20[/tex]
Weight of Sugar candies
weight of Sugar candies = weight of candy mix - weight of jelly bean
[tex]=100\ lb - 20\ lb\\= 80\ lb[/tex]
Total cost of sugar candiesTotal cost of candy mix = Total cost of jelly beans + total cost of sugar candies
[tex]100\ lb \times \$1.36 = (20\ lb \times \$0.20) + (80\ lb \times x)\\136 = 4 + (80x)\\136-4 = 80x\\132 = 80x\\x = \dfrac{132}{80}\\x =1.65[/tex]
Hence, the cost of 1 lb of sugar candies is $1.65.

3(7 – 2y) = 9
Please help. You have to solve it using distributive property. Thank you.
Answer:
3(7-2y)=9
Because there is no symbol between the 3 and the "(" we can tell that it wants you to multiply.
With the distributive property you must distribute the 3 within (7-2y)
To that you would multiply 7 by 3, and multiply -2y by 3. This would get you:
21-6y=9
To get y you must isolate it, the first step to isolate it is remove the number with no "y" next to it. Which is "21" Also for further problems your way, You should add/subtract/divide/multiple the number that does not have the same or even a variable as the variable you are trying to find to the other side.
In this case it would be subtracting 21 from the left side and subtracting it to the right side which would give us: 6y=-12
(Because there was already a number with no variable: "9" you will subtract 21 from 9 which is why you get -12).
Next you will further isolate the y by removing the -6. "-6y" means -6 multiplied by y. So you will divide -6 from the left side AND the right side.
-6y ÷ -6 = y ; -12 ÷ -6 = 2
y=2
More tips: When you are moving something to the other side always do the opposite to remove it from one side and move it to the other. Example: -12 + y = 5
You want to move the -12 to the right side. So you need to remove "-12" from the left side by ADDING 12 because -12 + 12 = 0.
Now you simply add it to the right.
Another example: 4y = 8
Because 4y is multiplication (4 times y) you must divide it from each side to isolate the y! : y=2
If you divide a number from the left side, you must also divide it from the right side. If you add a number on the left side, you must also add it on the right side. Same goes for subtraction and multiplication. Think like that!

x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)

Find the Area of the Shaded Portion:
inches squared
in sq
answer:
63 inches squared
step-by-step explanation:
in order to find the area of just the shaded portion, we would have to subtract the not shaded portion from the whole rectanglefirst, find the area of the whole rectangle1 ft = 12 inches (conversion)
12 X 6 = 72 in^2 (area of the whole rectangle)
now, find the area of the not shaded portion3 X 3 = 9 in^2 (area of the not shaded portion)
so, now that we have both areas, we just have to subtract them to find the area of the shaded portion72 - 9 = 63
- - > 63 inches squared

Step-by-step explanation:
A food pantry is making packages. Each package weighs 64 pounds. Each package contains 4 identical bags of rice and a 7-pound bag of beans. Write an equation to represent the situation.
Answer: ( . is another way to write a multiplication sign.
X = the amount of pounds each rice bag has.)
7 + 4 . X = 64
Not sure if this is needed but X = 14.25 so if there is a follow up question that asks how many pounds are in each bag of rice the answer would be 14.25.
If you can not use X in the equation another way of writing it would be 7 + 4 . 14.25 = 64
I am not sure which equation your teacher would want because that all depends on the teacher and if there are any further details on the question. So if somewhere on the question it said you have to use a variable you would use the equation with the variable.
Step-by-step explanation:
1. The question claims that the total of all of the pounds of rice and bean bas equals a total of 64 so that would be the answer to the equation.
2. You now need to make an equation that represents the situation by setting up your equation like this: 7 + 4 . X = 64
How to find X and have an equation with an already solved X.
1 We know that in total each bag has 64 pounds so that means we have to subtract 7 from 64. The difference is 57.
2. We now need to divide 57 by 4 because the rest of the bags have an identical amount of pounds so your answer should be 14.25.
3. Your equation should be set up like this: 7 + 4 . 14.25 = 64
