Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for
fencing. He knows that the area of the yard is 51 square meters and that the width is 5.2 meters longer
than the length. Which equation could be solved to determine the dimensions of the backyard, where the length
is / and the width is w?
0=w2+5.2w -51
o
0=12+5.21-51
4w + 10.4 = 51
о
41 +10.4 = 51
Answers
Answer:
The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
Step-by-step explanation:
As given,
The backward is rectangular in shape
Also , we know that
Area of rectangle = 2 ( Length + Breadth )
Also, given,
Breadth of the backyard = 5.2 + Length of the backyard
Let
length of the backyard = l
Breadth of the backyard = w
∴ we get
w = 5.2 + l
⇒l = w - 5.2
and
Area = 2 ( l + w)
⇒51 = 2( w - 5.2 + w)
⇒51 = 2 ( 2w - 5.2)
⇒51 = 4w - 10.4
So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
By solving we get
4w = 51 + 10.4
⇒4w = 61.4
⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35
⇒ w = 15.35
⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15
⇒l = 10.15
So the dimensions of the backyard = l × b = 10.15 m × 15.35 m
2. Solve x - 19 <81. Then graph the solution.
Answers
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
Right now, Molly is twice as old as Nancy. Zander is 6 years younger than Molly.
Which expression represents Molly’s current age in terms of Nancy’s?
Which expression represents Molly’s current age in terms of Zander’s?
Nancy is currently 10 years old, and Zander is 14. How old is Molly?
Answers
And let Nancy be x
Since molly is twice as Nancy
So equation is 2x=y
(Twice Nancy age is equal to Molly’s age)
2)let molly be y
Let zanders age be z
Since zander is 6 yrs younger than molly
So 6yrs added to zanders age equals Molly’s age
Eq: z+6=y
3) ) molly’S age =y,Nancy age =x
Since molly is twice as Nancy
So 2x=y. (Nancy is 10 .....given )
2*10 = 20
Or
molly =y
zanders =z
Since zander is 6 yrs younger than molly
Eq: z+6=y ( zandra is 14 ...given )
14+6=20

Solve the equation 3 (p-1) = 2p – 11.
Answers
Answer:
p = - 8
Step-by-step explanation:
3 (p - 1) = 2p - 11
3p - 3 = 2p - 11
3p - 2p = -11 + 3
p = -8
Answer:
p = - 8
Step-by-step explanation:
Given
3(p - 1) = 2p - 11 ← distribute parenthesis on left side
3p - 3 = 2p - 11 ( subtract 2p from both sides )
p - 3 = - 11 ( add 3 to both sides )
p = - 8

A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?
Answers
Answer:
$29.25
Step-by-step explanation:
The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.

Jenna won 77 toys playing basketball at her school's game night. Later, she gave four to each of her friends. She only has 9 remaining. How many friends does she have?
Answers
The equation can be written as:
77 - 4x = 9 where 77 is the total number of toys, 4 is how many toys she gave to each friend, x is the number of friends, and 9 is the toys remaining.
To solve for x, the number of friends:
77 -4x=9
Subtract 77 from both sides
77-77 -4x= 9-77
-4x= -68
Then divide both sides by -4 to isolate x.
-4x/-4 = 1x and -68/-4 = 17.
1x= 17, so the number of friends is 17.
1) Walter opened a bank account with $0. He deposits $200 in the bank
each month. Write an expression that represents how much money
Walter has deposited after some number of months (m). Which
student below is correct? What mistake do the other students make?
Student A
200*10
Student B
2200
Student C
200m
Student D
m = 200
Answers
Answer:
Student C is correct.
Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.
For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.
