Answer:
[tex]y^{10}-\dfrac{25}{64}x^2[/tex]
Step-by-step explanation:
Given expression:
[tex](\frac58x+y^5)(y^5-\frac58 x)[/tex]
Change the order of the terms in the first parentheses:
[tex]\implies (y^5+\frac58x)(y^5-\frac58 x)[/tex]
Apply the Difference of Two Squares: [tex](a+b)(a-b)=a^2-b^2[/tex]
[tex]\implies (y^5)^2-(\frac58x)^2[/tex]
Apply exponent rule [tex](a^b)^c=a^{b\cdot c}[/tex]
[tex]\implies y^{10}-(\frac58x)^2[/tex]
Apply exponent rule [tex]\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}[/tex]
[tex]\implies y^{10}-\left(\dfrac{5^2}{8^2}x^2\right)[/tex]
[tex]\implies y^{10}-\dfrac{25}{64}x^2[/tex]

what’s 34 + 2x = 49??? I NEED HELP
Answer:
x = 7.5
Step-by-step explanation:
Use algebraic manipulation (and remember that anything you do to one side must be done to the other, in most cases):
34 + 2x = 49
-34 -34
2x = 49 - 34
2x = 15
x = 7.5
What is the factorization of 49b2 − 81? (7b – 9)(7b – 9) (7b – 9)(7b 9) (7b2 – 9)(7b2 – 9) (7b2 – 9)(7b2 9).
answer : (7b+9)(7b-9)

Three students are playing a video game. Each player is randomly
assigned a character from a collection of characters that includes
5 blue, 6 green, and 3 red characters. After each character is picked,
it is not replaced in the collection.
1. What is the probability that the first player does not get a blue character?
Answer:
The probability the 1st player does not get a blue chracter is 9/14.
Step-by-step explanation:
So there is a total of 14 characters.
9 of them are not blue
9/14 = .642857 (~64%, not the answer since it's not asking for percents)
The probability the 1st player does not get a blue chracter is 9/14.

Hey there!
-√4x = 100
WELL….
-√4 = -2
NEW EQUATION:
-2x = 100
DIVIDE -2 to BOTH SIDES
-2x/-2 = 100/-2
CANCEL out: -2/-2 because it give you 1
KEEP: 100/-2 because it help solve for the x-value (mainly give you it)
NEW EQUATION: x = 100/-2
SIMPLIFY IT!
x = -50
Therefore, your answer is: x = -50

Graph attached~For what value of p are 2p + 1, 13, 5p – 3, three consecutive terms of AP?
Answer:
4
Step-by-step explanation:
The arithmetic progression terms, are
(2p+1), 13, (5p-3).
First find the distance between 2p+1 and 13.
[tex]13 -( 2p + 1 )= - 2p + 12[/tex]
Then find distance between 13, and 5p-3
[tex]5p - 3 - ( 13) = 5p - 16[/tex]
Terms in a AP progression should have same distances as each other.
[tex]5p - 16 = - 2p + 12[/tex]
[tex]7p = 28[/tex]
[tex]p = 4[/tex]
Answer:
Given 2p+1, 13 , 5p-3 are in AP. P is 4.
Can someone help with this math problem pleaseeee
Explanation:
The square root undoes the squaring operation.
Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.
Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.
I'm not sure why your teacher is using plus minus notation when that is not correct. Saying [tex]\sqrt{1} = \pm 1[/tex] is not true. The result of a square root is simply one value only. If your teacher meant [tex]\pm \sqrt{1} = \pm 1[/tex], then it would be a true statement; however, there's no need to involve negative numbers for this problem.

A hollow post is made out of a lightweight aluminum alloy that is 1.5 cm thick. The alloy is folded into the shape of a right rectangular prism measuring 9 cm by 9 cm by 28 cm. Find the total volume of alloy in the post. Round your answer to the nearest hundredth if necessary.
The total volume of alloy in the post is about 900 cm³
What is a volume?
Volume is the amount of space occupied by a three dimensional shape or object.
Volume = length * width * height
The right rectangular prism measuring 9 cm by 9 cm by 28 cm. The alloy is 1.5 cm thick.
Length = 9 - 1.5 - 1.5 = 6 cm, width = 9 - 1.5 - 1.5 = 6 cm, height = 28 - 1.5 - 1.5 = 25 cm. Hence:
Volume = 6 * 6 * 25 = 900 cm³
The total volume of alloy in the post is about 900 cm³

Two runners start the race at the same time. The first runner's speed is 4/5 of the speed of the second runner. After 30 minutes, the runners are 2 miles apart. What is the speed of each runner?
*not 1.78 & 2.22 :(*
Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.
What is a proportion?A proportion is a fraction of a total amount.
After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:
[tex]v_2 = v_1 + 4[/tex].
The first runner's speed is 4/5 of the speed of the second runner, hence:
[tex]v_1 = \frac{4}{5}v_2[/tex]
[tex]v_1 = \frac{4}{5}(v_1 + 4)[/tex]
[tex]\frac{1}{5}v_1 = \frac{16}{5}[/tex]
[tex]v_1 = 16[/tex]
[tex]v_2 = 16 + 4 = 20[/tex]
Hence, the speed of the runners are of 16 mph and of 20 mph.

The height of a trapezoid (h) measures 4 cm. Its shorter
base (b) measures 3 cm. A similar trapezoid has a
shorter base measuring 15 cm. Use proportional
reasoning to find the height of that similar trapezoid.
Answer:
20
Step-by-step explanation:
if two trapezoids are the same proportions, and one is 3cm, and the other is 15, the makes that second 5 times larger than the first. therefore, the height is also 5 times larger
4 x 5=20

Find the values of x and y.
Step-by-step explanation:
The figure shows an isosceles triangle. The two sides of an isosceles triangle are equal and the two base angles are equal. Since line AD is the angular bisector of the top Angle of an isosceles triangle, AD is also the base midline and base perpendicular bisector of the triangle.
So x=90 degrees.
The angles of a triangle add up to 180 degrees. So ∠DAC=(180-90-47)=43 degrees
y=43 degrees.
Answer:
y = 43°
x = 90°
Step-by-step explanation:
x = 90°(right angle)
y + 47 + x = 180(base angles of isosceles are equal)(all angles of triangle are equal)
y + 47 + 90 = 180
y + 137 = 180
y = 180 - 137
y = 43°
