Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{15 {x}^{4} + 13 {x}^{2} y + 2 {y}^{2} }}}}[/tex]
Option A is the correct option.
Step-by-step explanation:
[tex] \sf{(3 {x}^{2} + 2y)(5 {x}^{2} + y)}[/tex]
Use the distributive property to multiply each term of the first binomial by each term of the second binomial.
Thenafter, Simplify
[tex] \dashrightarrow{ \sf{3 {x}^{2} (5 {x}^{2} + y) + 2y(5 {x}^{2} + y)}}[/tex]
[tex] \dashrightarrow{ \sf{15 {x}^{4} + 3 {x}^{2} y + 10 {x}^{2} y + 2 {y}^{2} }}[/tex]
[tex] \dashrightarrow{ \sf{15 {x}^{4} + 13 {x}^{2} y + 2 {y}^{2} }}[/tex]
Hope I helped!

6(x-2)/12=2(x+1)/7
What does x equal?
Answer:
x=6
Step-by-step explanation:
1. First, distribute the numerator. That leaves you with:
[tex]\frac{6x-12}{12} =\frac{2x+2}{7}[/tex]
2. Now, cross multiply. You should have:
[tex]7(6x-12)=12(2x+2)[/tex]
3. Next, simplify and solve the equation for x. You should have:
[tex]7(6x-12)=12(2x+2)[/tex]
[tex]42x-84=24x+24\\42x=24x+108\\18x=108x=6[/tex]

Jennifer is saving money to buy a bike. The bike costs $246. She has $138 saved, and each week she adds $18 to her savings.
How long will it take her to save enough money to buy the bike?
Answer: 8 weeks
explanation: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.

Which is an accurate conclution regarding the system of equations below ? Y=2/3x-1 and Y=3-2/3x
Answer:
Lets start with the given system of linear equations In order to solve for one variable, we must eliminate the other variable. So if we wanted to solve for y, we would have to eliminate x (or vice versa). So lets eliminate x. In order to do that, we need to have both x coefficients that are equal but have opposite signs (for instance 2 and -2 ...

4.61 gallons of milk is sold for $14.86. If you have $21.32 in your wallet. How many
gallons of milk you can buy?
Answer:
You can buy approximately 6.6 gallons of milk.
Step-by-step explanation:
We can solve this problem by making a proportion:
4.61 gallons/$14.86 = x gallons/$21.32
By cross-multiplying, we get:
4.61 × 21.32 = 14.86x
98.29 = 14.86x
x = 6.6 gallons

100 points! Find the slope of the image.
Answer:
5/2
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
A has points ( -2,0) and (0,5) as points on the line
m = ( 5-0)/( 0 - -2)
( 5-0)/( 0 +2)
= 5/2
The lines B and C are parallel so they have the same slope 5/2
(-7,6) rotated 90 degrees

What is a set of numbers are intergers but not whole numbers or natural numbers?
If you have negative numbers anywhere in the set, then that set cannot be part of the whole numbers or natural numbers. This is because
set of whole numbers = {0,1,2,3,4,5,...}
set of natural numbers = {1,2,3,4,5,...}
The only difference is that 0 is not included in the set of natural numbers. Neither set has negative values in them.
So for instance the set {-5, 1,2,7} involves a number that is neither part of the whole numbers or natural numbers set. But every item listed is an integer
set of integers = { ..., -3, -2, -1, 0, 1, 2, 3, ... }
We can see that the integers is the set of positive and negative whole numbers, with 0 as well
Answer:
All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

1. Explain how you can use the algebraic representation to determine the new coordinates of a point.
Answer:
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
Step-by-step explanation:
In a two-dimensional plane, coordinates of a point define its exact location. The coordinate plane has two axes that are perpendicular to each other which are known as the x and y axis.
To find out the coordinates of a point in the coordinate system, follow the following procedure.
Begin at the point, draw a vertical line either up or down to the x-axis to get the x-coordinate.
Begin at the point, draw a horizontal line either to the left or right of the y-axis to get the y-coordinate.
The x-coordinate and the y-coordinate determine the new coordinates of a point.

1/3 (6x - 15) = 1/2 (10x-4)
Answer:
x = - 1Step-by-step explanation:
[tex] \frac{1}{3} (6x - 15) = \frac{1}{2} (10x - 4)[/tex]
Expand the terms in the bracket
That's
[tex] \frac{1 }{3} \times 6x + \frac{1}{3} ( - 15) = \frac{1}{2} (10x) + \frac{1}{2} ( - 4) \\ 2x - 5 = 5x - 2[/tex]
Subtract 5x from both sides
[tex]2x - 5x - 5 = 5x - 5x - 2 \\ - 3x - 5 = - 2[/tex]
Add 5 to both sides
[tex] - 3x - 5 + 5 = - 2 + 5 \\ - 3x = 3[/tex]
Divide both sides by - 3
[tex] \frac{ - 3x}{ - 3} = \frac{3}{ - 3} [/tex]
We have the final answer as
x = - 1Hope this helps you

The minimum thickness of the book is 53.8mm
Step-by-step explanation:
Given units/terms
400 pagesFront and back - 0.9mmEach page - 0.13mmSolution:
(0.9mm)(2) + (0.13mm)(400) = 1.8 mm + 52.mm = 53.8mm
Answer:
min. thickness of the book is 53.8mm
Step-by-step explanation:
400 pages, each page thickness = 0.13mm
front and back cover thickness = 0.9mm
total thickness of the book = front + 400 pages + back cover
total = 0.9 + (400 x 0.13) + 0.9
total = 0.9 + 52 + 0.9
total = 53.8 mm
