Por ejemplo, si x = 2a, entonces debajo de x^2 sera (2a)^2 = 4a^2.
Mismo va para y^2.
Para 2xy, haces el mismo. Por ejemplo, si x = 2a y y = 3b, 2xy sera 2(2a)(3b) = 2(6ab) = 12ab.
Sigues este pattern para la tabla.
Y para los otros cuestiones, yo te recomiendo que los “expand” y simplificas. (Lo siento español no es mi premier lenguaje)
Por ejemplo:
(4x^3 + 2y)^2
(4x^3 + 2y)(4x^3 + 2y)
(4x^3)^2 + 2(8x^3y) + 4y^2
* multiplicar los exponentes
4x^6 + 16x^3y + 4y^2
4(x^6 + 4x^3y + y^2)

If C is the midpoint of BD, what is the coordinate of point C if point B is at 0?
Answers
Answer:
It depends on where point D is placed so C > 0
Step-by-step explanation:
As i said above
We want to find the coordinate of C given that it is the midpoint of BD.
We know that B is at 0, so we can assume that each letter represents a position on the number line.
Then we can assume that D is located at a number different than zero, let's assume that D is located at the value d.
Then the segment BD goes from 0 to d, so its length is d.
Then the midpoint is at the middle, at d/2 plus the smallest value, 0:
C = d/2 + 0 = d/2

An airplane makes a round-trip supply run that takes a total of 6 hours and is 350 miles each direction. The air current going to the destination is
in the direction of the plane at 20 miles per hour. The air current traveling back to the starting point is against the plane at 20 miles per hour. Let
x represent the speed of the airplane, in mies per hour, when there is no wind.
Replace the values of a, b and c to create the equation that describes this situation.
Answers
Answer:
the anwser is x and it represents 350
Step-by-step explanation:
The speed of the airplane when there is no wind will be 116.67 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
An airplane makes a round-trip supply run that takes a total of 6 hours and is 350 miles in each direction.
The air current going to the destination is in the direction of the plane at 20 miles per hour.
The air current traveling back to the starting point is against the plane at 20 miles per hour.
Let x represent the speed of the airplane, in miles per hour, when there is no wind.
Then the speed of the airplane when there is no wind will be given by the average speed.
Then we have
x = (350 + 350) / 6
x = 700 / 6
x = 116.67 miles per hour

Please what is the answer of number 1
Answers
Answer:
-80
Step-by-step explanation:
First you multiply both sides of the equation by 5 to get rid of the fraction, it becomes Y + 30 = -50.
To get rid of the 30 you subtract 30 from each side and that makes it Y = -80.
Your answer does not want the Y=, so your answer is -80.

A sum of money is shared between two people in the ratio 19:14. If the first person receives 38 LE, how much money does the other receive?
Answers
Answer:
28 LE.
Step-by-step explanation:
Ratio Question:
The ratio of the money spent is 19/14. So you can create this equation:
19/14=38/x
Since they are the same ratio, this means that 38/x would equal 19/14.
Multiply both sides by 14 and x:
19x=532
532/19=x
x=28

Answers
Answer:
3y = 6 - 2 ( 0 ) take
x zero and find value of y
3y = 6 - 2 ( 0 )
3y = 6 - 0
3y = 6
both sides divide by 3
ans : y = 2
now we can find so the value of x
3y = 6 - 2x
3( 0 ) = 6 - 2x
when we find the value x we take y ( 0 ) zero
3 ( 0 ) = 6 - 2x
0 = 6 - 2x
0 + 6 = - 2x
6 = -2x
both sides divide by -2
ans or value of x is 3
Step-by-step explanation:
first
- find one of the values of x and y
two :
- when you solving this
take y ( 0 ) if you search / find the value of X

wheelchair ramp forms 20° angle with the ground. If the length of the ramp to the porch is 21.5 feet, how high (H) off the ground is the porch?
Answers
Answer:
The porch is 7.35 feet off the ground
Step-by-step explanation:
Trigonometric Ratios
The ramp, the height of the porch, and the distance from the base of both form a right triangle where trigonometric ratios can be applied.
The angle of 20° has the height of the porch H as the opposite side, and the hypotenuse is the length of the ramp.
The sine is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
For our problem:
[tex]\displaystyle \sin 20^\circ=\frac{H}{21.5}[/tex]
Solving for H:
[tex]H=21.5\cdot \sin 20^\circ[/tex]
Find the sine of 20° by using a calculator:
[tex]H=21.5\cdot 0.342[/tex]
H=7.35 feet
The porch is 7.35 feet off the ground
